| 摘 要： | 针对荷载规范中对大跨悬挑屋盖结构风振系数计算的不足,利用时程分析法,在有限元建模的基础上,直接采用风洞试验数据,计算了某大跨悬挑屋盖结构的荷载风振系数和位移风振系数,研究了其随风向角的变化规律,并讨论了不同风向角下结构参数的影响。

| Abstract: | Against the deficiency of calculation on wind-induced vibration factor of large cantilevered roof specified by load code for the design of building structures,wind-induced vibration factor of a large cantilevered roof is calculated,adopting time domain analysis,based on finite element model and data obtained from the wind tunnel test.The regularities of wind load factor changing with wind direction is studied,and effect of different structure parameters on the wind load factor of the structure under differe... |
