摘要
针对某大跨度单层网壳钢结构工程,进行强度和稳定性研究.在描述工程概况和分析工具的基础上,建立了相应的分析模型,确定了荷载情况和组合工况.进行静力分析,确定最不利工况,进行强度校核.利用两种有限元分析软件建立模型,分别进行线性和非线性屈曲分析,可知两种分析模型之间的误差很小,该单层网壳现有的设计方案稳定性好.
The intensity and the stability analysis of a large-span single-layer latticed dome steel construction is carried out.Based on the description of the construction overview and the analysis tools,the corresponding analysis models are established;the load and the combined conditions are decided.The static analysis is done to decide the worst condition and the intensity is checked.Models are set up with the help of two kinds of finite element analysis software.By means of the linear and nonlinear analysis of the bucking,it is clear that the error between the two analysis models is very small.The stability of the present design of the single-layer latticed dome is good.
