安庆长江公路大桥索塔锚固区受力分析

Mechanical analysis of anchorage area of cable support tower of Anqing Changjiang Highway Bridge

文章应用SAP84结构计算通用程序中的AUTOMESH3D模块对箱形索塔进行了分析,充分利用程序的自动化,避免了手工划分的简化。通过实际分析计算,对多边形索塔的受力机制进行了一定的剖析,根据索塔受力的实际工况,给出结构特征点处的应力值,给设计和施工提供了一定的参考,为新型索塔的设计和模型建立提出了一种新方法。

The mechanical analysis of the box tower for cable support is carried out by using the module AUTOMESH3D of SAP84.Based on the analysis of the actual condition of stress on the cable support tower,the values of stress on the special area of the tower are given. The obtained results are beneficial to the design and construction of the cable support tower. The presented work provides a new method for the analysis and modeling of the new type of cable support tower.
