The objective of this study is to investigate the failure modes of steel coupling beam-wall connection. Test variable of this study is types of material used, concrete and with pseudo strain hardening cementitious composites (PSH2C). The results showed that Specimen PSH2C-SB with longer embedment length of steel coupling beam exhibits good seismic performance than Specimen HCWS-SB.

An theoretical study of the strength of hybrid coupled shear wall connections is achieved. The bearing stress at failure in the concrete below the steel coupling beam section is related to the concrete compressive strength and the ratio of the width of the steel coupling beam section to the width of the hybrid coupled shear wall. Also experimental studies are achieved to revise shear transfer strength across connections between coupled shear walls and steel coupling beam. The main test variables were auxiliary details of stud bolts. In this studies. these proposed equations are shown to be in good agreement with the test results reported in the paper and with other test data in the literature.
