高层框架-核心筒结构考虑加载方式及混凝土收缩徐变影响下的竖向位移差分析

摘要

以某工程的60层框架-混凝土核心筒混合结构体系为对象,用有限元软件sap2000对其进行了施工期间的竖向变形分析.在计算中考虑了加载方式、混凝土收缩徐变等因素.重点探讨了施工期间混凝土的时变性对框架-混凝土核心筒混合结构体系承重构件的竖向变形规律.%A vertical deformation analysis on the 60-story mixed structure was performed use the sap20O0. The load simulation methods and the time-varying performance of concrete were considered. The load simulation methods and the time-varying performance of concrete are focused on the effect of Vertical Deformation of the mixed structure considering.
