Abstract:The calculation method of the story lateral stiffness of the high-rise building structure was discussed. In combination with engineering examples, several current different calculation methods were used to compare and analyze the lateral stiffness and the lateral stiffness ratio of the stories. The calculation results show that for complex high-rise building structures, the story lateral stiffness calculation method in literature ［3］ can better reflect the impacts on the story lateral stiffness by sudden changes in floor height, vertical member section changes, ring truss stories and outrigger stories. Therefore, the calculated story lateral stiffness ratio can accurately determine the weak story of the structure, which can be used as a reference in the design of engineering projects.

Keywords:story lateral stiffness; story lateral stiffness ratio; high-rise building structure
