INELASTIC TIME-DEPENDENT STRUCTURAL ANALYSIS METHOD FOR HIGH-RISE BUILDINGS

摘要：

　　For the traditional inelastic time-dependent analysis method,the force time history was obtained by the elastic time-dependent analysis and then the inelastic deformation time history was then derived based on the force time history.The impact of deformation time history on the force time history was not considered by traditional inelastic time-dependent analysis method.In fact,the differential inelastic deformation of different structural members will induce redistribution of the forces of high-rise structures during the construction,and the redistribution of forces will in turn change the inelastic deformation of different structural members.The mutual influence between deformation time history and force time history is called the time-dependent coupling effect.In this paper,a more accurate method of the inelastic time-dependent analysis was proposed for high-rise structures by considering the time-dependent coupling effect between force time history and inelastic deformation time history.The case study illustrated that the time-dependent coupling effect will have a significant impact on the structural responses during the construction of structures.
