摘要
网架结构自重小、空间刚度大,可以在较少支撑条件下实现较大的跨度,是目前广泛使用的一种结构形式。特别是加油站,由于受到场地限制,很多采用两点支撑的网架体系,但这种体系在外观上,由于下部结构简洁,上部大尺寸悬挑,给人以头重脚轻的感觉,被认为是不稳定结构。通过工程实例,对加油站小型罩棚两点支撑网架结构的安全性进行研究和分析,并总结两点支撑的网架结构综合力学性能特点,为此类结构形式的安全使用和推广提供参考。
The space truss structure has some good characters, such as little weight, good space stiffness, bigger span with less support pillar. It is one of the widespread structure models now. Especially in gas station, because of the area limit, two pillar support structure is a popular structure model. But in the appearance, this kind structure seems very instability due to bigger size suspend. Via an engineering example, it researched the safe character of this structure model, and summed up the multiple mechanical properties of this structure model which could offer an suggest for popularization and safe use with this structure model.
