The objective of this study is to investigate the behavior and strain characteristics of steel coupling beam-wall connection. Test variable of this study is embedment length of steel coupling beam in the embedment region. The results showed that Specimens PSH2C-ST and PSH2C-ST experienced bearing failure, based on the observation of strain of concrete in the embedment region.

The objective of this study is to investigate the seismic performance of hybrid coupled shear wall connection with new toughness material, pseudo strain hardening cementitious composites (PSH2C). Test variable of this study is the embedment length of steel coupling in connection region. The results showed that Specimen PSH2C-ST with longer embedment length of steel coupling beam exhibits good seismic performance than Specimen PSH2C-STE.
