摘　　要：通过建立树形柱与屋面整体的空间模型,对几何形状为弧形的树形分枝,用SAP2000进行屈曲分析,对不同部位的加载,得出的计算长度系数,分析得出理想结果。树形柱与屋面形成整体空间结构,分析内力进行设计,总结此类树形分枝的设计特点。对于异形截面框架柱,通过其截面特性,配合规范中的公式,对截面的承载力及稳定性进行设计复核,运用软件生成柱P–M–M曲面,对异形截面柱进行中震弹性承载力复核。柱与分枝连接节点处为刚接,通过采取构造手段,避免分枝构件与柱截面相贯焊接,从而避免节点处处于复杂应力状态。同时,总结了施工过程中的控制重点。By establishing the whole spatial model of the tree column and roof,the buckling analysis of the tree branch with arc geometry is carried out with SAP2000,and the calculated length coefficient obtained from the loading of different parts is analyzed to obtain the ideal result.The tree column forms an integral spatial structure with the roof,analyzes the internal force for design,and summarizes the design characteristics of this kind of tree branch.For the frame column with anisotropic section,through its section characteristics and in combination with the formula in the code,the design review of the bearing capacity and stability of the section is carried out,and the column P-M-M surface is generated by software to review the medium earthquake elastic bearing capacity of the column with anisotropic section.The connection node between column and branch is rigid connection.By adopting structural means,the intersection and welding of branch members and column section can be avoided,so as to avoid the complex stress state at the node.At the same time,the key control points in the construction process are summarized.
