高赞大桥有限元仿真分析

有限元仿真分析是随着计算机软硬件技术的快速发展而发展起来的一门工程技术,是未来结构设计与分析的发展方向。文章针对高赞大桥的实际情况,尝试利用个人计算机进行全桥全块体单元模型的第三层次仿真分析,分析中考虑该桥的施工过程、二期调索以及后期的收缩徐变效应。分析结果精度较高,可有效地指导设计工作,同时也说明了利用个人计算机进行结构高层次的仿真分析已经成为现实。

Finite Element Simulation Analysis of Gaozan Cable Stayed Bridge

Finite element simulation analysis is an engineering technology developed with the rapid development of the hardware and software for computers and is the orientation of development in future structural designs and analysis.In the light of the actual conditions of Gaozan Cable Stayed Bridge,third-level simulation analysis of block element model of the overall bridge structure was made by using personal computers,in which the construction process of the bridge,readjustment of cables and the shrinkage and creep effect in the later stage were considered.The result of the analysis showed high precision and can be of effective guidance for designs,indicating that it has become a reality to utilize personal computers to carry out higher-level simulation analysis of structures.
