long span roof structure 大跨屋盖结构
Although the different forms of these long-span roof structure,they have some common features,such as generally light, larger flexibility,low damping and natural frequency. Wind load is one of the control loads in the structure design.
尽管这些大跨屋盖结构的形式不尽相同,但它们都具有一些共同特点,即质量轻、柔度大、固有频率低、阻尼小等特点,它们都属于风敏感结构,因而风荷载就成为设计这些屋盖结构的主要控制荷载之一。
