In order to study the simplified calculation method of internal forces and displacements of steel frame-prestressed concrete anti-slip-force wall assembled system (SPW system) under horizontal load, a simplified calculation model of the structural system is proposed. Based on the elastic theory, the equilibrium differential equation , The parameter λ which reflects the lateral stiffness of the structure is proposed and the formula for calculating the internal force and lateral displacement of the structural system under uniform lateral load, inverted triangular lateral load and top concentrated lateral load is obtained by combining the boundary conditions. The finite element The method verifies the reliability of the simplified calculation method and carries out the error analysis. The results show that the finite element analysis is close to the simplified calculation, and the simplified calculation method can calculate the internal force and displacement of SPW system under horizontal load with good reliability.
