摘　　要：采用沿高度方向连续化方法,对考虑地基及楼板变形的框架—剪力墙结构进行协同分析。把每榀抗侧力单元看作竖放的铁摩辛柯梁,通过弹性楼板协同工作,并考虑地基变形的影响,导出框架—剪力墙结构协同分析的哈密顿正则方程。通过M atlab编程,用精细积分法求出问题的高精度数值解。Based on the continuum approach, a cooperating analysis of wall -frame structure considering ground and floor deformation is presented in this paper. Each lateral resisting structure is regarded as Timshenko beam placed vertically, through elastic floor joint operation and consider the influence of ground deformation, then infers the Hamihonian canonical equations of the question. With Matlab programmed, then precise integration method is used to solute the numerical solutions with high accuracy of the question.
