Abstract:: In order to research the simplified calculation method of the internal force and displacement for steel frameprefabricated concrete lateral force resisting wall structures (SPW system) under lateral load, the simplified calculation model of the structural system was put forward. Meanwhile, the equilibrium differential equations of the structural system were established according to the elastic theory, and the parameter λ standing for structural lateral stiffness was proposed. Then, based on boundary conditions, the calculation formulas of internal force and lateral displacement were deduced under uniform lateral load, inverted triangle lateral load and topconcentrated lateral load. The reliability of the simplified calculation method was verified by finite element method, and the error analysis was carried out. The study results show that the results of simplified calculation method are close to those of finite element method, the simplified calculation method can calculate internal force and displacement of SPW system under lateral load with enough accuracy and better reliability.
