摘要
通过对空间网壳结构在温度变化下的有限元数值计算,本文采用子空间迭代法系统研究了网壳杆件在不同温度场作用下不同矢跨比球面网壳的变形和受力性能。结果表明日照温差减小了支座水平推力,但对杆件内力影响较大。
The static analysis of latticed shell structure in different temperature condition is analyzed by using the finiteelement numerical calculation method.Based on ratio of the rise span and different temperature condition,Mechanical and deformation performance of single layer ellipse reticulated domes are studied with the method of sub space iteration.The results show that the horizontal thrust of supports is decreased under the temperature difference of sunshine,but there are influences greatly to internal forces of members.
