Unfavorable geometric imperfections in steel plate girders subjected to localized loads
(Elsevier, 2021)
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 ...
A simplified matrix stiffness method for analysis of composite and prestressed beams
(Techno Press, 2017)
The paper presents the simplified matrix stiffness method for analysis of composite and prestressed beams. The method is based on the previously developed "exact" analysis method that uses the mathematical theory of linear ...
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 ...
Verification of deflection according to Eurocode 2
(Wiley-Blackwell, 2017)
Code provisions for a simplified check of the long-term deflection of concrete structures are generally developed for predefined values of the relevant input parameters. Deflection calculation may be of interest to account ...
Shear deformable dynamic stiffness elements for a free vibration analysis of composite plate assemblies - Part I: Theory
(Elsevier Ltd, 2017)
A procedure for developing the dynamic stiffness matrix of a completely free laminated composite plate based on the first-order (FSDT) and higher-order shear deformation theory (HSDT) is presented. The proposed method ...
An efficient beam-column element for inelastic 3D frame analysis
(Springer Netherland, 2013)
Beam-column elements with section resultant plasticity for the hysteretic behavior of the end plastic hinges are widely used for numerical simulations in earthquake engineering practice because of the good compromise between ...
Cyclic plasticity of trusses
(Springer Verlag, 2015)
In this paper, the Preisach model of hysteresis, which was already successfully implemented for solving problems of cyclic plasticity of axially loaded bar and cyclic bending of elastoplastic beam, is extended to the ...
Geometric nonlinear analysis of prismatic shells using the semi-analytical finite strip method
(Elsevier Ltd, 2017)
The present study sheds light on geometric nonlinear static analysis of prismatic shells using the semi-analytical finite strip method. A new computational model, which includes a fully nonlinear compound strip with a ...
Matrix Stiffness Method for Composite and Prestressed Beam Analysis Using Linear Integral Operators
(Springer Verlag, 2015)
In the paper, the analysis of composite and prestressed beams using the matrix stiffness method is presented. The stiffness matrix for the frame element with a moment release at one end and the vector of equivalent nodal ...
Positive impact of 3D CAD models employment in descriptive geometry education
(Gliwice: PTGiGI, 2019)
Classical Descriptive Geometry (DG) course used 2D drawings for 3D spatial elements representation. Computer graphic introduced simulation of a 3D geometric environment in contemporary DG teaching. Research aim is the ...
