Stud bolt effects on the bearing performance of pseudo strain-hardening cementitious composite (PSH2C) wall-steel coupling beam connections

摘要

Recently, hybrid coupled shear system, where steel coupling beam couple two or more RC shear walls are frequently applied for medium and high-rise building subjected to earthquake. This paper addresses the seismic performance of PSH2C wall - steel coupling beam with stud bolts in the connection region. Test variables included stud bolts in embedded steel coupling beam and types of material, such as PSH2C and concrete, in the wall. The results show that PSH2C wall - beam connections (PSH2C-ST and PSH2C-SB) exhibit better hysteretic response than normal concrete wall - beam connections (HCWS-ST and HCWS-SB).
