【摘要】 普通门式刚架设计已有较成熟的技术规程和相关设计软件,对于高度较高、跨度较大的非常规门式刚架设计,可以借助有限元软件ANSYS进行分析。通用有限元软件ANSYS广泛应用于土木工程结构中,但对于具体工程分析使用不方便。结合工程实例,运用ANSYS参数化编程语言编译门式刚架的整体建模、求解、结果分析的专用分析程序,对门式刚架的工况组合、地震设计反应谱、地震波作用和模拟风场作用下时程响应的分析程序简要介绍,对解决类似工程具有较好的通用性。更多还原

【Abstract】 Much developed technical specifications and corresponding design software apply to the common portal frame design,while the higher and longer-span uncommon portal frame are analyzed by using ANSYS.The general finite element software ANSYS,which is widely used in the civil engineering fields,is inconvenient to the concrete projects.In this paper,ANSYS Parametric Design Language(APDL) is adapted to compile exclusive analytical program for integral model-building,solution and results analysis of the portal frame.Combined with an engineering case,the analytical program is concisely introduced for loadcase combinations,seismic response spectrum,seismic and simulation of wind field time-history response of the portal frame.It can be used for solving other similar projects.更多还原
