摘　　要：钢管树状结构作为仿生结构受力合理,但设计困难。结合具体工程,总结了分杈类和曲线缠绕类两类典型的树状结构形式。探讨了两类钢管树状仿生结构的稳定性设计方法。通过理论推导和有限元验证,对树状结构稳定性设计时计算长度系数的取值方法提出了建议,供工程设计时参考。The dendritic structure with steel tubes which is a kind of bionic structures has rational mechanical behavior,but is hard to design.A summary was made on two types of dendritic structures with steel tubes in engineering cases.The methods of stability design of the two types of dendritic bionic structures with steel tubes were discussed.It is advised to determine the magnitude of effective length coefficient when designing the stability of dendritic structure through theoretical derivation and finite element methods.The principles are proposed for design of the structure.
