英文摘要	Multi-limb shear walls and the relevant composite structures are essential components of high-rise structures in modern designs. However, it is inaccurate to demonstrate the core method that calculating the internal force of multi-limb walls in codes, specifications, and textbooks of civil engineering, in which the superposition distribution method is adopted to solve the differential equations for the restrained moment of coupling beams. In this paper, a new method is proposed to solve the inertial forces and displacements of three limb shear walls under three types of horizontal loads, and the analytical equations are given. The method solves the restrained bending moment of coupling beams by transforming the two second-order differential equations into the four first-order differential equations. Then the fundamental solution matrix is obtained for the coefficient matrix of differential equations. By comparing the internal force calculated by these two methods with those from Midas, it is found that the results from the traditional method are 10% less than those from the FE method and the new method. Besides, the new method improves the traditional way by avoiding the concept of distribution factor, the stiffness and the relevant position of coupling beams, and the integrity of the shear wall, etc. The proposed new method can provide reference for the expression of internal forces and displacements in composite structures of shear wall and frame. © 2019, Editorial Office of China Civil Engineering Journal.
