摘要
本文采用壁式框架来分析框架─剪力墙结构的非线性地震反应，假定弯曲刚度沿杆轴按抛物线分布，导出了考虑剪切变形的单元刚度矩阵，将古典刚度法或高斯消元法用以形成该时间间隔内的瞬时抗侧移刚度矩阵，用适合非线性动力计算的数值方法求解动力方程。
In this paper, a method is presented for analysing the nonlinear dynamic response of R/C frame-wall strUctUre tinder a strong earthquake motion. Based on the assumphon that the bending stickness of injured member is in a parabolic distribution, a nonlinear element stirness matrix is derived, considering the influence of shear deformation of the member itSelf. The classical stickness method and the Gaussian elimination method are used to form the matrix of transient drift-resisting stickness. Two new unconditionally stable integrate schemes suggested by the authors are used to compute nonlinear seismic response of R/C frame-wall strUctUres.
