Seismic performance of pseudo strain-hardening cementitious composite coupling beams with different reinforcement details

This paper addresses the seismic behavior of pseudo strain hardening cementitious composite (PSH2C) coupling beams with different failure modes in hybrid coupled shear wall. Test variables included the ratio of steel coupling beam strength to beam-wall connection strength. The results show that Specimen PSH2C-SCF exhibits a better stable behavior in comparison with Specimens PSH2C-SBVRT and PSH2C-FCF.

Wall System

Hybrid coupled shear wall system with steel coupling beams has known as the effective lateral load resisting system for tall buildings subjected to earthquake. This paper addresses the influence on horizontal ties of steel coupling beams in pseudo strain hardening cementitious composite (PSH2C) hybrid coupled shear wall. Test variables included the connection detail and types of material, concrete and PSH2C, in the connection region. The results show that Specimen PSH2C-SB and PSH2C-SBVRT exhibits a better stable behavior than Specimens HCWS-SB and HCWS-SBVRT.

Steel Coupling Beams

Hybrid coupled wall systems, where steel coupling beams couple two or more pseudo strain hardening cementitious composite (PSH2C) shear wall can be used in medium and high-rise construction subjected to earthquake. This paper addresses the panel shear strength of steel coupling beams - PSH2C shear wall connection. Test variables included the connection detail in hybrid coupled shear wall system. The results show that Specimens PSH2C-PSFF and PSH2C-PSFFT exhibits greater panel shears strength than Specimen PSH2C-PSF.

Shear System

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).
