巨型框架结构是未来超高层建筑结构体系发展和应用的主要方向之一,为了克服目前巨型框架结构分析过程中节点和单元数过于庞大、构造复杂、耗时较长等不利因素,通过将巨型梁、柱、支撑简化为具有等效轴向刚度、等效弯曲刚度及等效剪切刚度的等效实腹梁、柱和支撑的方法,简化建模难度,节约机时,实现变参数分析的目的.文中推导了等效简化的过程和方法,并以某一超高层杆件体系为例进行验算,结果表明等效简化效果明显.
Mega-frame structure is one of the main directions for the development and application of super-tall building structural system in the future. In order to overcome the unfavorable factors such as too large number of nodes and units, complicated structure and long time-consuming in the mega-frame structure analysis, , Columns and supports are reduced to equivalent real webs, columns and supports with equivalent axial stiffness, equivalent bending stiffness and equivalent shear stiffness, which simplifies the modeling process and saves time and variable parameter analysis The paper deduces the equivalent simplification process and method, and takes a super high-rise member system as an example for checking, the results show that the equivalent simplification effect is obvious.
