Abstract
Introducing openings in masonry shear walls reduces their stiffness and strength and alters their response to lateral loads. Prediction of post-cracking stiffness is required for calculation of building period in seismic design and for lateral load distribution. A research program was conducted at Drexel University to study the lateral response of reinforced masonry shear walls with openings through testing ten 1/3-scale walls under in-plane loads. Different sizes and locations of openings were considered. The test specimens were designed to behave mainly in a flexural mode by forming plastic hinges at the member ends. The test results showed that, for flexural-dominated reinforced masonry solid shear walls and shear walls with openings having the same overall dimensions and flexural reinforcement arrangement, the post-cracking stiffnesses and ultimate lateral load strengths are proportional. Based on the results of this study, a simple model was proposed to predict the post-cracking stiffness of reinforced masonry shear walls with openings.
