摘要:
基于传统悬索桥成桥状态计算方法,应用有限元法,提出了一种基于ANSYS有限元分析的确定多塔悬索桥主缆成桥线形的迭代算法.在此基础上,进行了3～6塔悬索桥试设计,针对试设计方案的合理成桥状态进行了算例分析,并与重力刚度理论计算结果进行了对比.算例表明,利用该方法可以准确地得到多塔悬索桥的成桥线形和内力.该方法不仅可以应用于平面缆索体系的成桥状态分析,同样也适用于空间缆索体系.
Abstract:
Based on the traditional calculation method of the finished state of suspension bridge and the finite element method, an iterative algorithm for determining the finished alignment of the main cable of multi-tower suspension bridge is proposed based on Ansys Finite Element Analysis. On this basis, the trial design of 3-6 tower suspension bridges is carried out, and the calculation results are compared with those of gravity stiffness theory. An example shows that the finished alignment and internal force of multi-tower suspension bridge can be obtained accurately by using this method. This method can be applied not only to the analysis of finished state of plane cable system, but also to the analysis of space cable system.
