The calculation model for the collaborative analysis of frame-shear wall structure was established by considering partial floor deformation,the flat 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.
