Abstract
In the composite shear wall frame system proposed by authors, steel coupling girders function as hysteretic dampers. RC shear wall panels are designed such that the panels behave elastically when exposed to a large seismic excitation. A series of dynamic analysis was performed in order to investigate ductility demand for the coupling girder, as well as the force response of the shear wall. The use of steel wide flanges as the coupling girders was found sufficient by comparing the cumulative plastic deformation demand and test data. Design shear and flexural force for the RC wall panel, as well as the design tensile force for the wall base, was obtained using the analytical results.
