Computed Nonlinear Seismic Response of R/C Wall-Frame Structures

摘要

This study presents a method of nonlinear analysis for the response of a R/C coupled shear wall and/or wall-frame structure subjected to strong earthquake motion. The objective is to maintain relative simplicity in the method itself, yet produce reasonable reliability in the computed results. The computed responses of one cantilever column member, two coupled shear wall structures, and one wall-frame system under dynamic loads and static loads are compared with the available test results. The effects of moment-axial force interaction of wall members as well as the effects of pinching action and strength decay of coupling beams on overall computed responses of the coupled shear wall structures are discussed.
