摘要
以有限元程序ANSYS为计算平台,以一多层钢框架结构为研究对象,分别进行了平面和空间结构的可靠性分析,并运用蒙特卡罗法、响应面法进行了结构整体可靠性的计算。通过对比可得出:以空间结构为计算模型,运用基于响应面的蒙特卡罗法进行数值模拟计算可得出较好的计算效果。
Based on FEM ANSYS, the reliability of the spatial steel frame and the plain steel frame are studied respectively and the integral reliability of a multilayer steel frame construction is calculated and analyzed through comparison by using Monte Carlo method and response surface method respectively. The result shows that, when spatial structures are used as computation model, the precision and efficiency of Monte Carlo method based on response surface are excellent over conventional Monte Carlo method.
