In this study, nonlinear finite element (NLFE) analysis is conducted to determine the maximum shear capacity (Vmax) of stiffened steel plate walls (SSPSW) with rectangular openings. Results a wide range parametric study are presented using developed response surface method (RSM), which quantified effect prominent input variables on predicted SSPSW. The studied parameters, evaluated by different...

For this purpose a finite element model specifically developed for the nonlinear analysis of steel-concrete composite beams is adopted. This finite element model includes material nonlinearity of slab concrete, reinforcement steel, beam steel as well as slabbeam nonlinear partial interaction due to the deformable shear connection. The inclusion of the partial interaction in the composite beam m...

Although studies on RC beams under shear have a history record of more than 100 years, many important issues in this context still remain that have evaded attention. The aim of the current study is to study a number of these less investigated aspects of the behavior of RC beams under shear. For this purpose, and based on the modified compression field theory, a computer program has been writte...
