| Many efforts have been made to monitor the cracking behaviour in RC structures. The objective of this paper is to present the results of a theoretical study aimed at monitoring the behavior of coupled shear walls supported on two columns in elastic and post elastic stage, also drift at each story, stress and strain for both concrete and steel reinforcement, and crack propagation. Consequently, a case study was assumed, where three-dimensional, non-linear finite element analysis was carried out for eighteen samples taking into consideration cracking and crushing of concrete, as well as yielding of rebars. The results were reported as the effect of characteristic strength, stiffness ratio between columns and walls, on the ultimate horizontal load capacity and the ductility of the entire system. The results demonstrate that stiffness ratio between shear walls and supporting columns is more crucial on the response of the coupled system rather than characteristic strength, and the position of first flexural and shear cracks are predominated by transfer beam stiffness. | ||||
