【摘要】 介绍了蒙特卡罗法和响应面法两种数值分析方法各自的特点,再以有限元程序ANSYS为计算平台,利用ANSYS所提供的APDL(参数化设计)模块进行可靠性计算与分析。分别运用蒙特卡罗法、响应面法对一多层钢框架结构进行了结构整体可靠性的计算与对比分析,从计算结果可得基于响应面的蒙特卡罗法的计算精度和计算效率都要优于传统的蒙特卡罗法。更多还原

【Abstract】 The characteristic of Monte Carlo method and response surface method are introduced in the paper.By using the ANSYS parametric design language,the reliability is calculated.The integral reliability of a multilayer steel frame construction is calculated and analyzed by using Monte Carlo method and response surface method respectively.The result shows that the precision and efficiency of Monte Carlo method which based on response surface are better than conventional Monte Carlo method.更多还原
