ANSYS优化设计在确定斜拉桥恒载索力中的应用

On application of ANSYS optimal design in identification cable-stayed bridge of dead load cable tension

以主梁和主塔的最大位移最小(塔直梁平)为目标,介绍大型有限元分析软件ANSYS的优化设计功能及其在确定斜拉桥成桥恒载索力的实现过程,并结合实桥应用效果指出采用ANSYS进行斜拉桥成桥恒载索力确定是比较方便可行的。

Aiming at the minimum largest displacement of the main beam and the main tower with straight towers and flat beams, the study intro- duces the optimal design function of the large-scale finite element analyzing software ANSYS, and its realization process in identifying the cable- stayed bridge dead load cable tension, and indicates that it is feasible and convenient to adopt ANSYS to identify the dead load cable tension of the cable-stayed bridge by combining with its application effect in factual bridges.
