摘要
采用Marc非线性有限元程序对广州新白云国际机场主航站楼在恒荷载、活荷载和风荷载作用下的变形进行了计算,对结构进行了动态分析,得到了前10阶振型周期和振型模态,通过对结构的动态计算可知,各阶振型的自振周期相差不大,同时结构存在共振失稳的可能。
The deformation of the air station building of new Baiyun International airport in Guangzhou, which is subjected to constant loads, varible loads and wind loads, was calculated by using the Marc nonlinear finite element program. The periods and the modes of vibration from the first to the tenth order of the building were obtained by the dynamic analysis of the structure. The dynamic computation of the structure shows that the period difference of the vibration modes is small. The vibration instability is possible for the structure.
