Based on the second law of thermodynamics, an open system shows a stable state where receives minimum energy or maximum entropy. Changes in input of the system leads to the new output, where system shows a new equilibrium ...

Dynamic relaxation (DR) is an iterative method for solving simultaneous sets of equations, which govern the behavior of static structures. One of the most effective techniques in this category is the kinetic damping approach. ...

The focus of this paper is on the force-based finite element for analysis of planar frames. Both material and geometrical nonlinear behavior are considered in this study. The formulations are based on the two-field Hellinger-Reissner functional...

Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive ...

This research is dedicated to propose a high-performance locking-free triangular plane element, which is based on the novel mixed finite element formulation. The new element has six nodes with two transitional degrees of ...

the effects of TMD in elastic structures .This paper aims to evaluate the application of TMD as a passive controlling system for structures considering nonlinear behavior. Tow 4 & 8 story reinforced concrete buildings designed based on Iranian code are modeled...

, the structural responses converge to the accurate static solutions. Nonlinear behavior of structures includes various characteristics, such as the existence of load limit points; displacement limit points, buckling points, post-buckling region and bifurcation...

into consideration. The nonlinear behavior of these structures are studied by PERFORM 3D software and its multi-layer shell finite elements with fiber sections. Carrying out the analysis, the performance level of each model is determined...
