Analysis of frame structure vibrations induced by traffic
(Croatian Association of Civil Engineers, 2013)
A simple numerical model for the dynamic analysis of 20 frames in the frequency domain, based on the Spectral Element Method (SEM), is presented in the paper. The influence of soil-structure interaction is taken into ...
Damage detection via dynamic characteristics determination / Otkrivanje oštećenja određivanjem dinamičkih karakteristika
(Institut za ispitivanje materijala, Beograd, 2005)
The change of dynamic parameters (stiffness, damping), as a consequence of structural history (erosion, friction, fatigue, internal damages and cracks), has an impact on decrease of reliability and serviceability of a ...
Discrete Kirchof theory of thin shells based on triangular finite element, I / Diskretna Kirchofljeva teorija tankih elastičnih ljuski izvedena iz trougaonog konačnog elementa, I
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2002)
Assuming convected coordinate frame, a three node triangular shell element which uses a discrete Kirchof bending formulation is presented. The tangential components and transverse displacement are approximated by complete ...
Rotation-free isogeometric analysis of an arbitrarily curved plane Bernoulli-Euler beam
(Elsevier B.V., 2018)
The present study elucidates linear static analysis for plane beam structures using the isogeometric approach. A novel methodology for rotation-free analysis of an arbitrarily curved Bernoulli-Euler beam in the convective ...
Numerical analysis of reinforced concrete frame buildings with decoupled infill walls
(Building materials and structures, 2020)
Reinforced concrete (RC) buildings with masonry infill walls are widely used in many countries all over the world. Although infills are considered as non-structural elements, they significantly change dynamic characte-ristics ...
Hysteretic behavior of rectangular tube (box) sections based on Preisach model
(Archive of Applied Mechanics, 2012)
In the present paper, the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular ...
Cylindrical Mirror Anamorphosis and Urban-Architectural Ambience
(Birkhauser Verlag AG, 2015)
Cylindrical mirror surfaces fall into the group of reflecting surfaces that give a distorted image of an object. However, if the object is designed according to the laws of optical geometry, in a way that its mirror image ...
Experimental and numerical research on damage localization in plate-like concrete structures using hybrid approach
(John Wiley and Sons Ltd, 2018)
This paper presents an experimental-numerical analysis of damage localization of concrete plate-like elements on the basis of hybrid approach. The proposed hybrid approach uses the fast discrete wavelet transform, energy ...
Torsional buckling of thin-walled beams in presence of bimoment induced by axial loads
(Strojarski Facultet, 2015)
In this paper the influence of the bimoment induced by external axial loads on the elastic torsional buckling of thin-walled beams with open cross-section is studied. The governing differential equations of a deformed ...
Stability Calculation of the Plane Steel Frame Structures Using Tangent Modulus Theory
(Hindawi, 2023)
This paper considers the phenomenon of the instability of steel plane frame structures in the elastic-plastic domain. The numerical analysis uses FEM, where the corresponding stiffness matrices are based upon the trigonometric ...
