Verification of structural performance of connections between reinforced concrete shear walls and outriggers in high‐rise buildings
https://orcid.org/0000-0002-0215-0497
The outrigger and belt truss system is the most commonly used lateral load‐resisting system for high‐rise buildings in which the external mega columns and core walls are connected via outriggers and belt trusses. The shear studs, which are used for the connections between the outriggers and the core walls, are subjected to pull‐out loading because of the lateral load. Although various types of shear studs have been developed based on analytical and experimental studies, most previous studies on the behavior and strength of shear studs have been based on push‐out tests. It is necessary to verify the structural performance of shear studs subjected to pull‐out loading before their field installation at the connections in the structural system of high‐rise buildings. In this study, experiments were conducted on full‐scale pull‐out test specimens made of materials having the same strength as those used in an actual high‐rise building structure. The experimental results show that the shear strength of the connection can be improved by approximately 7.9% using double‐headed studs instead of normal‐strength studs.
