Sometimes, it is necessary to install regular openings like windows or doors in the shear walls. Such openings require special reinforcement. There are several methods for reinforcing deep beams, one of which is the use of fiber reinforced polymer bars. In this study, an experimental work on a coupled shear wall has been used to mode the system by using finite element method with ABAQUS software. The finite element model was established based on part of the experimental study and verified with the other parts of the experimental results. The comparison shows good agreement. In the study, three different types of fiber reinforced polymer bars were considered in improving the mechanical and structural behavior of RC coupling beams. Results of the finite element analysis showed the superiority of the CFRP bars in improving seismic behavior of the coupled shear wall comparing to GFRP and BFRP.

“…Well-detailed steel coupling beams with small span/ depth ratio are stiff and strong, and they possess stable hysteretic behavior according to a number of past studies (Shahrooz Bahram, Remmetter Mark, and Fei 1993;Harries Kent et al 1993;Park and Yun 2005;Cheng, Fikri, and Chen 2015;Bengar and Aski 2016;Li et al 2018;Lu et al 2018). In addition to achieving better performance, steel coupling beams offer economic advantages over RC coupling beams.…”

Hybrid coupled wall (HCW) systems, especially with properly designed steel coupling beams, are efficient lateral load resisting systems. To further improve the seismic resiliency of HCW structures after major earthquakes, a new hybrid system consisting of steel plate composite structural wall piers and steel coupling beams with a replaceable fuse was developed. This paper presents an experimental program of three half-scaled subassemblies subjected to pseudo-static cyclic loading. Each test specimen consisted of two segments of composite wall piers and a steel coupling beam with and without a replaceable fuse. The details of the wall piers were identical for the three subassemblies, but three different coupling beams with the same span/depth ratio were used. One subassembly using a steel coupling beam without a replaceable fuse served as the control specimen, which was loaded up to 10% chord rotation following a preselected loading protocol. The other two specimens employed the new hybrid system. The fuse in these two subassemblies was replaced in situ after subjecting the coupling beam to 2% chord rotation, and the specimen was subsequently loaded up to 10% chord rotation. A detailed evaluation of the test results indicates that the new hybrid system can exhibit excellent performance and the replaceable fuse (and its connection details) proved to be a reliable technique to restore the performance after subjecting the coupling beam to chord rotations that are expected during design-level earthquakes. The load transfer mechanism and seismic performance varied depending on the details of the replaceable details of steel coupling beams.

“…Large‐scale experimental comparative study on coupled shear wall, with SLBs versus traditional CLBs, was rarely reported. Two recently published experimental comparative studies of coupled shear wall system were finished by Kim et al and Cheng et al Kim et al proposed a new kind of link beam with a U‐shaped steel plate damper in the middle and then conducted a comparative test against the coupled wall with reinforced concrete (RC) link beams (RCLB). The test results showed that the RC wall piers connected by the link beam with U‐shaped damper presented excellent seismic response over conventional coupled RC shear walls.…”

Summary This paper aims to investigate the seismic performance improvement effect of coupled shear wall with steel link beams under cyclic lateral loading. The quasi‐static tests on two 1/3‐scaled specimens, including one coupled shear wall with steel link beams and one coupled shear wall with conventional concrete link beams, were conducted. These two specimens were designed with similar lateral initial stiffness and tested under the same gravity and lateral cyclic loading procedure. The specimen with concrete link beams exhibited sequence shear failures of link beams from top to bottom storey after completing 22 loading cycles. However, the specimen with steel link beams sustained ductile and plump hysteretic behavior under the same loading cycles. The lateral load‐resisting capacity of the specimen with steel link beams is 2.2 times of the specimen with concrete link beams. The experimental results demonstrated great advantages of steel link beams in improving seismic performance of conventional coupled shear wall systems.
