The Wall–Frame Interaction Effect in Corrugated Steel Shear Walls Systems

Steel shear wall with corrugated plate is a lateral load resistant system. In recent years, researchers have made investigations in this Field. In this study, the behavior of this system under pushover loading has been evaluated. For this purpose, 20 samples of steel shear wall system with corrugated plate with bay to height ratio of 0.85,1.4,2,2.5 And in 1,2,4,6,10 Stories has been designed. Then these samples with finite element software (Abaqus) were analyzed. Results of this study show that the initial stiffness of this type of shear walls is high And it's resistance in drift about 0.1 percent reaches to the highest amount. But when the plate is subjected to interaction buckling it's stiffness and resistance has been decreased significantly. Also, Results of this study shows that before the plate reaches to buckling limit; a greater percentage of shear force is resisted by plate but after plate's buckling frame has more contribution in resisting shear force. In this study mechanism of creation of tension Field in this type of systems has been evaluated and relation for determination of tension Field's angle was proposed. In the end, in this study, a method for estimating pushover diagram of shear wall system with corrugated plate for one and several story structures has been presented. This solution was founded on the interaction between frame and corrugated Plate and by results of experimental and numerical samples was verified.
