【Abstract】 Wall-frame method can be used to calculate the forces and displacements of shear wall structures with large openings,in which the linear rigidity of coupling wall-beams is larger than or close to the linear rigidity of coupling wall-columns.However,when the ratio of height to length is large,if the shear deformation is not considered in the wall-frame method,the results may be not accurate.Two methods of calculating structural internal force and deformation are given in this paper.A 10-story shear wall structure with large openings is analyzed by universal finite element method of SAP2000t,he influence of shear deformation on working perfor-mance is discussed,and some reasonable suggestions are given to guide engineering practice.更多还原
