应用STAAD CHINA设计变电构架

Using STAAD CHINA in Substation Truss Design

在500kV变电站中,变电构架是最主要的构筑物,使用空间结构计算分析软件来完成变电构架的静力分析,与平面计算相比,更符合结构实际受力性能,计算结果更精确。常用软件有STAADCHINA空间分析软件。变电构架属于排架结构,可按空间杆系结构或空间桁架结构进行分析计算。结构建模时应注意整个结构必须是不变体系,所有节点必需是稳定的节点。变电构架荷载在人工输入时,设计人员可根据经验,对荷载进行定性分析,保留具有控制作用的荷载工况和荷载组合。

Substation truss is the uppermost structure in a 500 kV substation. Compared to planar structure calculation, using the spatial structure analysis software to perform static analysis is more consistent with actual loading conditions and results are more accurate. The STAAD CHINA Version is a popular spatial structure analysis software. Substation truss belongs to frame structure, so that it can be treated as a space truss. Note that during structural modeling, the entire structure must be stable and all the nodes must also be stable. During manual load input, designers can qualitatively analyze loads based on experiences and keep important working condition and load combinations.
