| Abstract |
Since a ductile coupled shear wall system is the primary seismic load resisting systems of many structures, a coupling beams of these system must exhibit excellent ductility and energy absorption capacity. No specific guidelines are available for computing the bearing strength of steel coupling beam-wall connections in a hybrid wall system. We have carried out analytical and experimental studies on steel coupling beams- concrete wall connections. The bearing stress at failure in the concrete below the embedded steel coupling beam section is related to the concrete compressive strength and the ratio of the width of the embedded steel coupling beam section to the thickness of the shear walls. The test variables included the reinforcement details that confer a ductile behaviour in the steel coupling beam-wall connection, i.e., the auxiliary stud bolts attached to the steel beam flanges and the transverse ties at the top and the bottom steel beam flanges. Proposed equations were in good agreement with both our test results and other test data from the literature. |
