摘要
对某农业园区大跨度阳光温室大棚,采用立体钢管桁架拱结构形式,通过改变各榀桁架拱跨度、曲率的方式,形成椭圆曲面的建筑造型。对大棚结构进行静力分析,动力特性分析,研究其整体受力性能。分析结果表明:此类结构刚度较大、整体稳定性好,是一种受力性能较好的屋盖结构形式。
A large-span construction plane, by c sunshine greenhouse of an agriculture park adopts steel hanging the spans and curvatures of truss arches. Static truss arch structure and ellipse analysis and dynamic character- istics analysis were conducted to study the integral resistance behavior. It is shown that the roof with good struc- tural rigidity and overall stability is of well mechanical performance.
