斜拉立体桁架结构是一种造型优美,有着较好结构形式的杂交体系。目前对于此种结构已有学者做了许多研究,但是风荷载部分相对比较空白。对斜拉立体桁架建立模型,模拟其在单独竖向风作用和单独水平风作用两种工况下的风振响应状况,并对其进行分析,得出一些供类似工程参考的结论。 Cable-stayed three-dimensional truss structure is a beautiful shape, has a better structure of the hybrid system. At present, many scholars have done a lot of research on this kind of structure, but the wind load part is relatively blank. The model of inclined three-dimensional truss was established, and the wind-induced vibration response under two different vertical winds and single horizontal winds was simulated and analyzed. Some conclusions for reference of similar projects were obtained.
