Nonlinear Dynamic Seismic Response of R/C Frame-Wall Structure

In this paper, a method is presented for analysing the nonlinear dynamic response of R/C frame-wall structure under a strong earthguake ground motion. Based on the assumption that the bending stiffness of injured member is in a parabolic distribution, a nonlinear element stiffness matrix is derived for any distributions of moment. with the conception of rotation ratio as well as the model of rigi d-bar frame introduced, the matrix of transient drift-resisting stiffness is also derived, The nonlinear seismic response of R/C frame-wall structure is then analysed.The calculated results show that this method can explain and predict very well the possible damage and collapse caused by earthquake.
