利用蒙特卡洛模拟技术以及基于Spearman秩相关系数的灵敏度分析方法,对工程常用的16种K6型单层球面网壳进行了参数分析.利用ANSYS进行了64000次双重非线性模拟运算并对计算结果进行了统计分析,得到了其弹塑性稳定极限承载力对于所有杆件的灵敏度值.总结了K6型单层球面网壳不同位置杆件对其弹塑性稳定极限承载力的影响规律,并对计算分析结果进行了验证.
Sixteen kinds of single-layer K6 single-layer reticular shells commonly used in engineering were analyzed by using Monte Carlo simulation technology and sensitivity analysis based on Spearman rank correlation coefficient.Using ANSYS, 64000 double nonlinear simulation operations were carried out, and the calculation results The statistical analysis shows that the sensitivity of the elastic-plastic ultimate load-bearing capacity to all the members is obtained.Analysed the influence of different members of the K6-type single-layer reticulated dome on its elastic-plastic stability ultimate capacity, The results of the analysis were verified.
