摘要
设计了钢管混凝土三肢柱塔架,建立了塔架的有限元模型,并利用SAP2000软件对钢管混凝土三肢柱塔架进行了弹塑性地震分析.通过分析可得:在罕遇地震作用下,钢管混凝土三肢柱塔架大部分的构件处于弹性阶段,仅在顶端和底端有少数构件进入塑性阶段.在地震波作用的后期塔架顶部的位移达1.1 m,稍小于塔架高度的1/50(1.26 m).
The concrete-filled steel tube 3 limbs column tower was designed and the finite element model of the tower was established,The elastic-plastic analysis was carriod on by using SAP 2000 software,which shows that under rare earthquake ,the majority of bars of the concrete-filled steel tube 3 limbs column tower is in the esastie stage ,with only a small number of bars at the top and the bottom into the plastic phase;in the post-selsmic,the displacement at the top of tower is 1.1 re,being slightly less than the tower height of 1/50（ 1. 26 m）.
