摘　　要：建立了考虑部分楼板变形的框架剪力墙结构协同分析的计算模型,将弹性楼板结构平面分成若干个区域,每个区域内的抗侧力结构可看做一个框剪单元,弹性楼板的作用看做框剪单元的弹性支座。在哈密顿力学的框架下导出了协同分析的对偶求解体系,进而利用精细积分法求出结构位移和内力的数值解。算例说明计算结果精度较高。The calculation model for the collaborative analysis of frame - shear wall structure was established by considering partial floor deformation, the fiat structure of flexible floor is divided into several regions, each of lateral force - resisting members can be seen as a frame - wall modules, and flexible floor role can be seen as a elastic support unit. The derived solving dual system for analysis of synergies was derived by using Hamiltonian mechanics; the structure of displacement and internal force of the numerical solution were derived by using precise integration method. Example calculation results indicate that the method is high precision.
