Numerical modelling of concrete-filled steel tube columns under axial compression
(International Congress Proceedings / Association of Structural Engineers of Serbia, 16. Congress, 2022)
The paper presents the numerical modelling of concrete-filled steel tube stub columns under axial compression. The nonlinear 3D finite element model for the analysis was developed using ABAQUS software. The modelling, ...
Estimation of ultimate strength of slender ccfst columns using artificial neural networks
(16th Congress of Association of Structural Engineers of Serbia, 2022)
This paper proposes the use of artificial neural network (ANN) algorithms to estimate the ultimate compressive strength of slender circular concrete-filled steel tubular (CCFST) columns. A dataset of 1051 samples was applied ...
Perception of three-dimensional geometric shapes as virtual 3D road markings
(Serbian Society for Geometry and Graphics Faculty of Technical Sciences, University of Novi Sad, Belgrade ; Novi Sad, 2018)
Excessive speed and poor driver perception are the causes of a large number of traffic accident. Analysis of the influence of geometry in driver behavior has been widely performed by different researchers. One way to improve ...
Slobodne vibracije rotaciono-simetričnih sistema primenom metode dinamičke krutosti / Free vibration study of axisymmetric assemblies using dynamic stiffness method
(Univerzitet u Beogradu Građevinski fakultet BeogradDruštvo građevinskih konstruktera Srbije, 2022)
U ovom radu primenjena je metoda dinamičke krutosti za analizu slobodnih vibracija sistema koji se sastoji od kružne cilindrične ljuske i kružnih i/ili prstenastih ploča. Pri formulaciji dinamičkih matrica krutosti korišćena ...
Preisach model for inner hysteresis loops of cyclicly loaded mild steel elements
(International Conference Synergy of Architecture and Civil Engineering, 2023)
In this paper, the new type of Preisach model, that describes the inner hysteresis looops of structural mild steel under cyclic loading, is developed. It is the multilinear mechanical model, that describes closed hysteresis ...
Impact of surroundings on the local peak pressure in high-rise building clusters
(AIM Group International, Italy, 2023)
This study contributes to the field of wind engineering by evaluating the local peak pressure coefficients in a generic high-rise building cluster. Unlike previous studies that have focused on isolated buildings or buildings ...
Experimental testing of axial load capacity and stability of circular CFT columns
(Serbian Society of Mechanics, 2019)
The paper presents the experimental testing of the axial capacity and stability of short,
moderately slender and slender circular CFT columns. For the purpose of sample testing a special
set of hydraulic presses was ...
Train-induced vibrations: moving load modelling
(13th International Symposium of MASE, Ohrid, Macedonia, 2009)
In this paper numerical modeling of train induced vibration is presented. The wheel force is modeled with assumption that only static component with constant load shape and constant velocity exists. The dynamic and inertial ...
Low-Cycle Fatigue Damage Model for Ductile Materials
(The Fourth International Conference on Damage MechanicsLouisiana State University, 2023)
In this paper, a uniaxial material model with the ability to describe progressive damage growth, but also to provide a reliable estimation of fatigue life in the low-cycle regime of loading, is presented. The determination ...
Prostorna interpretacija Hugelschaffer-ove konstrukcije jajaste krive
