Abstract |
In the last several decades, hybrid coupled shear walls with link beams have become increasingly recognized as efficient lateral load-resisting systems for mid- to high-rise buildings. The purpose of this study was to investigate the feasibility of alternative detailing for steel link beam-to-reinforced concrete (RC) wall connections, to simplify the complex reinforcement details outlined in the ACI CODE-318-19(22) design standards and to reduce the risk of brittle fractures in the connection region. The test variables of this study included the presence or absence of fiber, the embedment length of the steel coupling beam, and the inclusion of stud bolts and horizontal ties in the connection region. The results show that incorporating PVC fibers into the connections significantly enhances both the shear capacity and damage tolerance of the steel coupling beam-to-wall connection.
