seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
the steel shear wall and composite steel plate shear wall is introduced in recent three decade and is considered and is spread rapidly. composite steel plate shear wall which is made of a layer of thin steel sheet with coating of reinforced concrete in one or both sides of steel palate is considered a third generation of resistance shear walls against lateral loads that in addition to increasin...

during the last few decades, steel shear walls have been adopted as efficient lateral resisting systems for high rise structures and numerous researches have been conducted on their static and dynamic behavior. steel shear walls have been utilized for retrofitting existing structures, as well as in design of new buildings in japan and usa. in this research, we have focused on the optimization o...
Lightweight steel framing is a method in housing and construction that have been widely used in lightweight steel construction. In this method, the structure is built by cold formed steel elements. They are cost-effective, light, and easy to assemble. However, the performance of lateral load resisting systems in cold-formed steel structures specially the behavior of cold-formed steel shear wall...
In this study, non-linear behavior of diagonally stiffened steel plate shear walls as a seismic resisting system has been investigated, and theoretical formulas for estimating shear strength capacity of the system have been proposed. Several validated analytical finite element models of steel shear walls with various stiffener dimensions are generated to verify and compare the analytical and th...
A revised procedure for the design of steel plate shear walls is proposed. In this procedure the thickness of the infill plate is found using equations that are derived from the plastic analysis of the strip model, which is an accepted model for the representation of steel plate shear walls. Comparisons of experimentally obtained ultimate strengths of steel plate shear walls and those predicted...
In tall buildings the reinforced concrete (RC) shear wall is one of the predominant structural components used to resist lateral loads induced by earthquakes around the world. Previous research demonstrated that shear walls displayed a sudden loss in lateral capacity due to the wall corner and web crushing in the plastic zone. In addition, it was found that large shear distortions in shear wall...
In this paper, the nonlinear behavior of R.C frames strengthened by shear walls and steel bracings is investigated. The use of steel bracing and R.C shear wall for strengthening of existing R.C structures usually leads to very complicated system and the study of the behavior of this kind of structures especially their connections, steel bracing area, and frame - shear walls and bracing interact...
steel shear walls, like bracings are a resistance system against wind and earthquake loads, which have more advantages than other systems. this paper is investigating the influence of openings on steel shear walls under increasing static loads. for this purpose, the experiments of other researchers on finite elements method have been checked and after investigating the correctness and precision...
