Seismic Retrofitting of Reinforced-Concrete Coupled Shear Walls: A Review
Publication: Practice Periodical on Structural Design and Construction
Volume 25, Issue 3
Abstract
Coupled shear walls (CSWs) are structural systems connect two or more walls at the floor levels by reinforced concrete beams called coupling beams (CBs). These systems have good lateral stiffness and dissipation energy under lateral seismic loading. This paper introduces a comprehensive overview on the seismic behavior and state of the art regarding the conducted research as well as the codes provisions pertained to coupled shear walls systems. Many existing reinforced concrete buildings could suffer from some kinds of failure after strong earthquakes. Consequently, the most efficient and economic retrofitting system has to be figured out and implemented. Therefore, a broad overview on the adopted retrofitting techniques as well as upgrading systems for coupled shear walls is presented and compared. It was found that each retrofitting system came up with some advantages and disadvantages. Thus, the most efficient technique based on the required structural performance level as well as the total cost can be selected.
