某花瓣外形钢结构设计要点分析

Key points analysis of certain steel structure with petal appearance

结合具体工程实例,介绍了某花瓣外形钢结构的结构布置及设计难点,并通过计算选取有代表性的构件进行应力分析,得出一些有用的结论:扭矩是不可忽略的内力项;而且,对于这样的类似单层网壳钢结构,要从实际出发,须将其变形后的平衡状态作为实际变形状态进行建模计算。基于以上分析,为类似的结构设计提供参考。

Combining with the specific engineering examples, this paper introduced the structure arrangement and design difficulties of a petal shaped steel structure, and through the calculation and selection of representative components made the stress analysis, obtained some useful con-clusions ：the torque was an internal item that could not be ignored, moreover, for such a similar single layer reticulated steel structure, should be from the actual situation, made the equilibrium state after its degeneration as the actual deformation state to model and calculate. Based on the a- bove analysis, provided reference for similar structure design.
