In China, the high rise structures load code is used for the large span spatial structures, only the first frequency is taken account for the wind vibration analysis, which is not reasonable.
我国现在仍是采用高耸或高层结构的荷载规范,只取结构的第一阶频率计算风振系数,按此方法进行大跨空间网格结构的风振分析是很不合理的。
In wind speed time history simulation of large-span spatial structures, both time and spatial correlation should be considered.
大跨空间结构风速时程模拟需考虑风的时间相关性和空间相关性。
The spatial reticulated shells are dynamic-sensitive structures because of large span and spatial multiformity.
空间网壳跨度大、空间造型多样,往往属动力敏感性结构。
