AB  - Driven by the industry's needs to address energy dissipation issues in mechanical connections,
the set goals of the global scientific community, and previous research efforts to interpret how
the condition of contact surfaces between two bodies in contact can be significant, a unique
experimental setup has been devised to study the impact of the state of contact interaction
between two bodies on the system's response. The purpose of the designed experimental setup
is to correlate the roughness of contact surfaces with the deformation of a specially designed
experimental sample. The roughness of contact surfaces represents the most dominant
influencing factor in the contact interaction of two bodies. In terms of scale, the study,
measurement, and analysis of surface roughness fall under the micro and nano scales. On the
other hand, the change in deformation of the experimental sample as a result of the change in
roughness falls under the macro scale. Based on all the aforementioned, the fundamental idea of
the designed experimental setup can be seen. Considering that it is not possible to enter into
contact interaction and explicitly analyse the influence of roughness on the response of a
mechanical connection, the idea in overall research is to consider the macro behaviour of a
specially prepared experimental sample depending on the level of roughness of the contact
interaction surfaces at the micro level. The aim of this paper is to present details and challenges
in the construction of an instrument necessary for such precise examinations, named “Precision
Press with Arcs”.

AB  - The paper presents an experimental and analytical way of determining the impulse response of
a linear time-invariant damped system with one degree of freedom.
An experiment was conducted where the mass was excited by an impact load. Both the mass
acceleration and impact force values were recorded. The magnitude of the system's frequency
response was determined based on the recorded values, ensuring the relatively simple
identification of the system's basic parameters. Those parameters were used to define a suitable
mathematical model of the system, transfer function, and frequency response function in an
analytical form.
The impulse response of the system based on the recorded values of mass acceleration and impact
load is expressed as a discrete function. This function is determined by applying the inverse
discrete Fourier transform of the corresponding frequency response function.
The impulse response of the system, based on the mathematical model, is expressed as a
continuous function. This function is determined by applying the inverse Fourier transform of
the corresponding frequency response.
Finally, it was shown that the response of a system to arbitrary load could be determined by
convolving the impulse response of the system with the load function. Convolution of continuous
functions is difficult to perform, and it can be used only for the simplest problem and for
understanding the physical phenomenon. Discrete convolution has a practical utility because it
is easy to perform in some program languages like Matlab. However, discrete impulse response
has limitations depending on the test conditions.

AB  - The objective of this research is to develop a numerical model of one widely used bolted beam splice connection
that dissipates energy through structural damping. The reference experimental setup is carefully designed to
obtain the highly nonlinear dynamic response due to the suddenly released load. The fact that the monolithic
beam with welded connection has a linear response is utilized for the initial calibration of the numerical and
experimental models. Then, the numerical model of bolted beam splice connection is verified and adopted
through an iterative process. The influences of time and spatial integration, bolt load application, element
type, contact formulation, bulk viscosity, and mass scaling are discussed. A special attention is given to the
load application and load release functions. After the verification, the Abaqus/Explicit numerical model is
validated through the comparison with experimental data, where an appropriate friction coefficient is adopted.
It is demonstrated that the nonlinear structural damping occurs due to the complex micro slip behavior at the
contact interface.

AB  - The paper considers the influence of patch load length, flange thickness, and stiffener's characteristics
on the behaviour of steel plate girders subjected to patch loading in terms of elastic stability. The aim is
to show the dependence of the elastic critical load on the mentioned parameters, through the buckling
coefficients of the isolated web plate and steel I-girders subjected to patch loading.
The girder without transverse stiffeners in the load application zone, but with longitudinal stiffener was
analyzed. The buckling coefficients of clamped plate and I-girder are compared, and suggestions for
improving the EN1993-1-5 patch loading resistance model are presented. The paper gives a brief
overview of the ultimate load capacity of longitudinaly stiffened I-girders. Numerical results are
compared with the results of current standards EN1993-1-5.
The aim of this research is to single out the characteristics of the girders that have the greatest impact
on the elastic critical load. It is necessary to come up with new expressions for the calculation of the
buckling coefficient through more detailed and comprehensive analyzes. It is shown that the influence
of stiffener and flange cannot be neglected because both parameters are important.

AB  - Problems involving contact are of great importance in industry related to
mechanical and civil engineering, but also in biomechanics and other applications. The
contact interaction between surfaces in a bolted splice connection joint or area through
which tire interacts with the road is not known a priori, leading to a nonlinear boundary
value problem. Due to the rapid improvement of modern computer technology, today one
can apply the tools of computational mechanics to analyze contact problems with limited
accuracy, depending on design requirements. However, even now most of the standard
finite element software is not fully capable of solving contact problems, including friction,
using robust algorithms. The aim of this paper is to present some basic concepts of Contact
Mechanics. To illustrate the difficulties arising in computational contact mechanics,
Newton-Raphson scheme was used to solve simple 1D contact problem using penalty
method.

AB  - This paper presents the finite element modeling of bolted joints for structural
dynamic analysis to achieve a reasonable accuracy in simulation results. Non-linear
effects in splice connected joints involve normal compressive loads holding components
together combined with dynamic lateral loads inducing some amount of shear slip in
contact interaction between elements of splice connection joint. The complexities of the
slip process are responsible for the nonlinear nature of the interfaces, both in terms of
stiffness and dissipation. Exploring the physics of joints directly is not readily done
because key interactions takes place at the interface of surfaces, where instrumentation
cannot be placed without changing the problem. Consequences of the specific conditions
of joint connections are increased dynamic problems related to vibrations and dissipative
processes in structure connection joints. Structural joints are the main reason for the
significant level of energy dissipation and source of structural damping. The aim of this
paper is to present some problems regarding research of structural damping and the
importance of study Contact Mechanics to better understand the problem of structural
damping.

AB  - Recent experimental studies have shown that the current EN1993-1-5 patch loading resistance model underestimates the ultimate strength of steel plate girders in certain cases, especially for longitudinally stiffened steel plate girders and longer patch load lengths. In addition to this resistance model, the design standard allows the use of finite element analysis for the ultimate limit state. The existing design recommendations for an adequate ultimate limit state design are found insufficient. In the current paper, the imperfection sensitivity analysis of steel plate girders subjected to patch loading is performed. The paper presents a nonlinear finite element parametric study designed to determine the influence of a variety of geometric imperfections on the patch load resistance of longitudinally unstiffened and stiffened steel plate girders. Experimentally measured, buckling mode-affine, and hand-defined sinusoidal geometric imperfections were varied in the study in combination with varying patch load lengths and relative stiffnesses of the longitudinal stiffener.

The ultimate strength of longitudinally unstiffened and stiffened steel plate girders increases as the patch load length is increased for all the geometric imperfections considered. For relatively small patch load lengths, the relative stiffness of the longitudinal stiffener has no significant influence on the ultimate load regardless of the geometric imperfection. For longer patch load lengths, the ultimate strength is highly dependent on geometric imperfections. The influence of the web panel aspect ratio is shown to be negligible for smaller patch load lengths regardless of the geometric imperfection, while for longer applied loads, the impact of this ratio is dependent on the geometric imperfection.

Unfavorable geometric imperfections in steel plate girders subjected to patch loading are governed by the patch load length and the relative stiffness of the longitudinal stiffener. Different unfavorable geometric imperfections were found for different patch load lengths and relative stiffnesses. Local geometric imperfections defined in the upper web sub-panel yield lower ultimate strengths than global geometric imperfections (defined over the whole web depth). The lowest patch load resistances were returned for geometric imperfections that resembled the deformation at collapse (collapse-affine geometric imperfections). Although the concept of collapse-affine geometric imperfections seems impractical for design purposes (a geometrically and materially nonlinear analysis must be conducted before collapse-affine geometric imperfection shapes are determined), the use of these imperfection shapes is recommended.

AB  - The challenge that will be posed to researchers for an even longer period is
the development of a predictable model for describing mechanical connections, their
variable stiffness and dissipative contact interaction processes. The main challenge to this
goal lies in the lack of understanding of how friction behaves on a small scale. Coulomb
friction, a large heuristic model is not predictable and has actually been proven to be
untrue in many modes. Expecting a universal law of friction for all types of materials and
therefore contact interactions is not very realistic. Instead, the goal of the international
research community is to develop a predictable model for a limited range of cases. So far,
the metal-metal contact is most often tested, respectively the contact interaction behaviour
of aluminium and steel elements of different quality. We also know that in the application
those two metals are most often found in making mechanical connections. The aim of this
paper is to make a brief overview of some of the previous tests and approaches to the study
of contact interaction in mechanical connections and the role of friction in energy
dissipation.

AB  - The aim of this paper is to discuss numerical analysis and verification of experimentally tested bolted and weld splice connections in the commercial Abaqus software. The first step in verifying a numerical model with an experimental one is to compare the modal frequencies. The problems that arise when modeling multiple bodies in a contact interaction, such as in the case of bolted splice connection joint, arise from the behavior of the contact itself [2] and [1]. In order for the numerical model to be stable and without calculations convergence issue, it is necessary to: define an adequate type and size of finite elements, determine the master and slave surfaces, and properly define the constraints and connections of the separate parts of the bolted welded connection structure. Tests with a modal hammer were performed in order to find the oscillation tones of the cantilever beam under consideration, which would be compared with the numerical model. Based on a comparison of numerical and experimental results, it is discussed whether the experimental beam is adequately designed and constructed and the effects of the support and splice connections on the frequencies are considered.

AB  - Problems involving contact are of great importance in industry related to mechanical and civil
engineering, but also in biomechanics and other applications. The contact interaction between
surfaces and different bodies like in a bolted splice connection joint or area in which a tire interacts with the soil is not known a priori, leading to a nonlinear boundary value problem. Due to the rapid improvement of modern computer technology, one can today apply the tools of computational
mechanics to analyze contact problems with required accuracy, depending on design requirements. However, even now most of the standard finite element software is not fully capable of solving contact problems, including friction, with robust algorithms. The aim of this paper is to present some basic concepts of Contact Mechanich.

abstract = "Problems involving contact are of great importance in industry related to mechanical and civil
engineering, but also in biomechanics and other applications. The contact interaction between
surfaces and different bodies like in a bolted splice connection joint or area in which a tire interacts with the soil is not known a priori, leading to a nonlinear boundary value problem. Due to the rapid improvement of modern computer technology, one can today apply the tools of computational
mechanics to analyze contact problems with required accuracy, depending on design requirements. However, even now most of the standard finite element software is not fully capable of solving contact problems, including friction, with robust algorithms. The aim of this paper is to present some basic concepts of Contact Mechanich.",

AB  - Progress and demands of all types of constructions imposed the need for the development of modern structures that are lightweight, but at the same time have high damping capacity and stiffness. The consequences of these requirements are increased dynamic problems related to vibrations and dissipative processes in structure connection joints. Structural joints are the main reason for the significant reduction of the level of energy dissipation and source of structural damping so therefore they have become a subject of interest to many researchers. The aim of this paper is to present some problems regarding research of structural damping and the importance of study Contact Mechanics to better understand the problem of structural damping.

AB  - It is generally known that reinforced concrete frame structures with unreinforced masonry infills frequently suffer severe damage when subjected to earthquake loading. Recent earthquakes show that the damage occurs to both older buildings and new seismically designed buildings. This is somehow surprising as this construction type has been the subject of intensive research projects for decades and simplified verification concepts are available in standards. However, these concepts are based on the separate verification of in-plane and out-of-plane loading although the importance of the design for combined loading conditions is already known. This situation was the reason to perform comprehensive investigations of the seismic behaviour of this traditional construction type for separate and combined in-plane and out-of-plane loading within the framework of the collaborative European research project INSYSME (Innovative systems for earthquake resistant masonry buildings in reinforced concrete buildings). These investigations are helpful to develop innovative approaches to improve the seismic behaviour of infilled frames. This article presents the fundamental project results for experimental investigations on reinforced concrete frames filled with high thermal insulating clay bricks under separate, sequential and combined in- and out-of-plane loading. The test results clearly illustrates that the load-bearing capacity severely depends on the boundary conditions in the connection area between the infill and the frame.

for longitudinally stiffened girders. Initial geometrical imperfections of stiffened girders that correspond to de-
formed shape at the collapse (collapse-affine imperfections), especially in the zone where the load is applied,
will give the most unfavorable ultimate strengths. For the considered geometry in the present paper, the third

AB  - The paper presents an analysis of the influence of vehicle speed movement
along bridge on dynamic amplification factor for the case of simply supported, continuous
and clamped beam structural system. The analysis was conducted analytically and
numerically. Theoretical expressions was developed for the case of movement a
concentrated force over the bridge over simply supported beam structural system, while
other cases were analyzed numerically. Two cases, movement of concentrated force and
system of concentrated forces were considered. The comparative results for the most
unfavorable case, with the valid domestic and foreign regulations, compared and
presented. The results showed that it is a more unfavorable case when vehicles are moving
at higher speeds on short-span bridges, as well as that one concentrated force produces
greater dynamic effects than a system of concentrated forces, as well as the simply
supported beam system is the most sensitive on dynamic loads respect to other structural
systems.

The tests are made on a model of a simple beam with cantilevers. Two heuristic optimisation techniques are used in the proposed procedure for detecting the location and level of damage: taboo search and simulated annealing. The results show that both proposes procedures, with appropriate target functions and weight factors, are highly efficient for detecting the location and level of damage.

Stoga se može reći da je zbirka prvenstveno namenjena studentima konstruktivnog modula, sa namerom da se olakša savlađivanje gradiva koje se izlaže u okviru predmeta Dinamika konstrukcija i zemljotresno ineženjerstvo na četvrtoj godini studija. Takođe, biće korisna i studentima modula Menadžment, tehnologije i informatika u građevinarstvu za savlađivanje predmeta Teorija konstrukcija 2. Zbirka sadrži ukupno trideset šest rešenih zadataka, koji predstavljaju izbor zadataka sa pismenog dela ispita u poslednjih deset godina. Pretpostavka je da studenti poseduju osnovno znanje koje se odnosi na gradivo predmeta Statika konstrukcija i Matrična analiza konstrukcija, koji su inače i uslovni predmeti za polaganje predmeta Dinamika konstrukcija i zemljotresno ineženjerstvo, kao i dovoljno teorijsko znanje iz predmeta Dinamika konstrukcija i zemljotresno ineženjerstvo. Rešenja prikazana u zbirci su data sa objašnjenjima neophodnim za suštinsko razumevanje problema pri rešavanju zadataka. Redosled zadataka u zbirci je izabran sa namerom da se postepeno savlađuju problemi, uz preporuku studentima da vežbaju zadatke po redosledu kako su dati u zbirci. Autori će sa zahvalnošću prihvatiti sve primedbe čitalaca zbirke, koji žele da ukažu na moguće nedostatke i koji imaju svoje predloge za njeno poboljšanje.

AB  - The paper presents overview of damage detection of structures using non destructive test methods and corresponding optimization procedures for detection, localization and severity of damage. Change of a stiffness, as a consequence of damage existence, reflects on changes of structural modal properties. Ambient vibration measurement, with corresponding identification of modal properties, is presented in detail because of its high importance for the whole damage detection process. The key benefit of the application of these methods is the ability to conduct tests without disrupting the function of structures. Also, there are presented the basic elements of detection and localization of damage using modern heuristic optimization methods.
AB  - Rad prikazuje pregled metoda oštećenja konstrukcija primenom nedestruktivnog testiranja, kao i odgovarajućih metoda optimizacije koje se primenjuju za lokalizaciju i karakterizaciju ozbiljnosti konstrukcijskog oštećenja. Promena krutosti, kao posledica oštećenja, odslikava se u promeni modalnih karakteristika konstrukcije, što se široko primenjuje u detekciji oštećenja. Merenje ambijentalnih vibracija, sa odgovarajućom identfikacijom modalnih karakteristika, je detaljno prikazana zbog velikog značaja u procesu detekcije oštećenja. Ključna pogodnost za primenu ovih metoda je mogućnost izvršenja testiranja bez remećenja funkcije konstrukcija. Takođe, prikazani su osnovni elementi detekcije i lokalizacije oštećenja primenom savremenih heurističkih metoda optimizacije.
