【摘要】 以响应面法为核心,使用APDL语言编制了结构可靠度分析程序,与ANSYS强大的有限元分析功能相结合,可以直接对大型结构进行可靠度分析。本程序可以自由选择可靠度分析的随机变量,定义极限状态方程并计算可靠指标。首先用若干算例对程序进行了验证,然后对国内某一大跨度悬索桥进行了静力可靠度分析,得到的结果合理可靠。更多还原

【Abstract】 The response surface method (RSM) is realized with the help of ANSYS Parametric Design Language (APDL). Connected with the powerful finite element analysis tool, it can be used directly for the reliability analysis of large structures. The selection of random variables, the definition of limit state functions and calculation of reliability index are available and convenient in this program. The static reliability analysis of one suspension bridge in China is analyzed after several other examples are verified. All the results are reasonable and reliable.更多还原
