Abstract |
The more demands on efficient utilization of resources, the more structural engineers prefer to select remodeling to improve old building's capacity. A series of four shear wall specimens were tested under constant axial stress and reversed cyclic lateral loading in order to evaluate the effect of the opening on the lower center of the wall induce by remodeling. Consequently, the existence of opening was verified to induce a different failure, which was caused by reduction of compression strut area formed on the wall to diagonal direction. Especially, the ultimate strength of the wall with an opening was revealed approximately 35% lower than that of the wall without an opening. And the similar results were appeared in characteristics of stiffness and energy dissipation capacity.
