In this paper, load-carrying capacity in steel shear wall (SSW) was estimated using artificial neural networks (ANNs). The SSW parameters including load-carrying capacity (as ANN’s target), plate thickness, thickness of stiffener, diagonal stiffener distance, horizontal stiffener distance and gravity load (as ANN’s inputs) are used in this paper to train the ANNs. 144 samples data of each of th...

Seismic rehabilitation provides existing buildings with more resistance to seismic activity, ground motion, or geotechnical failure due to earthquakes. Performance-based rehabilitation is a general concept through which the retrofitting criteria are defined regarding to performance objectives when the structural and nonstructural members are subject to different levels of earthquake hazards. In...

Although studies on RC beams under shear have a history record of more than 100 years, many important&#10issues 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 writ...

A new type of strengthening technique for existing reinforced concrete (RC) shear walls was proposed using steel wire mesh (SWM) and polymer mortar. The experimental campaign consists testing one conventional RC wall specimen four specimens strengthened different configurations ratios wrapping methods under cyclic lateral loading. results showed that the application meshes mortar not only delay...

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...
