摘　　要：针对钢管树状柱的受力特点,利用空间桁架的内力平衡条件和能量原理,给出了钢管树状柱在垂直荷载作用下的手算方法,计算结果与用有限元方法分析的钢管树状柱符合较好,为计算机分析提供了一个校核方法。The methods of simplified calculation of dendriform-column subjected to vertical loads are presented. The methods for calculating dendriform-column are provided by use of the conditions that the forces on each node are in equilibrium and that the energy principle of space truss. The results obtained by the present method are in good agreement with the those of FEM analysis.
