摘　　要：以308m高的六安市广播电视塔工程项目为背景,以球形塔楼与外塔架之间转换部位的关键节点为研究对象。采用大型通用有限元软件仿真计算的方法,研究了不同主管壁厚、不同内加劲板宽度、厚度、设置的位置及数量的改变对节点的承载力的影响,最终给出了相对较合理的节点优化方案。Based on the project of the 308m high rise-radio and television tower in Luan this paper took the key joint of the transition truss between the spherical turret and the outer brace as the research object.the finite element software simulation method were used to calculated the influence of the joint bearing capacity with the change vary from wall thickness internal stiffener width thickness setting position and number.Finally a relatively reasonable joint optimization scheme were given.

关 键 词：广播电视塔 节点有限元分析及优化 节点承载力 应力水平
