摘　　要：以大型通用有限元分析软件ANSYS为开发平台,以结构非线性分析方法为基础,利用参数化有限元分析技术开发多层钢框架结构升板施工模拟软件。利用自主开发的计算机仿真软件,采用节点约束释放技术可以方便地了解钢结构升板过程中构件的内力和变形,通过对3～6层钢框架升板过程屈曲载荷的分析,找出升板过程中结构的薄弱位置所在,为结构设计和结构吊装方案的选择提供技术支持。The simulation software based on ANSYS for the lift slab construction of the multi-storey steel frame is developed with the parametic finite element analysis technology. Taking the node constraint release technology can know the stress and deformation of the components during the lift slab construction through the self-developed computer simulation software, the weak position of the structure is obtained by the analysis of the buckling load of the 3 to 6 storey steel frame during the lift slab construction, it can provide technical support to the structure design and the chosen of the structure hoisting schemes.
