| 摘 要： | 利用大型有限元软件对矮塔斜拉桥分丝管式的索塔锚固区建立了非线性接触模型,通过定义模拟拉索与鞍座的接触关系,探讨了鞍座处混凝土的应力分布情况和索力传递分配情况,并与等效线荷载计算模型进行对比分析,结果表明:接触算法更接近实际受力情况.

| Abstract: | A nonlinear contact model for anchorage zone of cable tower with strand-separatingtubular-saddle was established via large-scale finite element software;simulating contact relation between cable and saddle by contact pair was carried out;stress distribution in the concrete on tower wall was discussed as well as transfer and distribution of cable force based on exquisite simulation calculation for the model.Comparative analysis of model through equivalent linear load was conducted.Results indicated that contact algorithm was close to actual level. |
