【提要】 由钢筋混凝土主框架与钢次框架组成的混合巨型框架有三种施工方案。为了探讨不同方案下巨型框架的受力性能，以4跨24层巨型框架结构为例，采用有限元软件MIDAS，考虑次框架梁柱与主框架梁柱为半刚性螺栓连接的影响，对比分析了其梁柱弯矩与主框架柱节点的位移。结果表明，三种施工方案下均需考虑施工过程带来的不利影响，且不同施工方案下相应的部位需加强配筋。

Abstract:Mageframe structure is composed of main and hypoframe, which has goo
d behaviors, and can be built by different ways according to construction schedule. Based on semirigid connection joints between main frame beamcolumn and hypoframe beamcolumn, the results of a 24story mageframe structure with 4 span were calculated by the universal finite element method of MIDAS,and the mome
nts and medal column joints displacements were compared between nonconsidering construction process and three kinds construction order. The influence of construction o
rder on behaviors of madeframe structures considering semirigid connection is discussed, and  suggestions are put forward in engineering practice.
