Nonlinear and Post-Buckling Behavior of Concrete Frames Reinforced by Thin Steel Plate Shear Wall

Authors

Abstract

In recent decades, to reach the lateral load resisting system which can satisfy a set of parameters, strength, hardness and flexibility, a lot of researches have been done. In recent years, in many countries, a new system called, steel plate shear wall (SPSW) has been used. Due to hardening and high strength, high energy absorption capability, speedy erection, economical and easy performance, the system has been used more in rehabilitation of existing steel buildings. While SPSW system can be easily integrated into existing steel frames, its suitability in concrete frames is still in the developmental stage. Currently on the behavior of reinforced concrete frame reinforced with SPSW research work has been slowly, because of have varied and complex behavior, researchers have always been interested in the use of concrete and steel together. In this study, first the numerical model has been verified by experimental results and then the behavior and the phenomenon of post-buckling in concrete frames reinforced with SPSW has been discussed. The results shows the suitable behavior of structure reinforced with SPSW and thereby it indicates load capacity, stiffness and energy absorption and flexibility of system increased. The actual drift ratio of floors using SPSW was also significantly reduced.
