| 摘 要： | 自锚式悬索桥在施工中要通过吊杆张拉实现体系转换,各工况下吊杆力往往要依靠手工试算、反复迭代来确定,工作量较大。利用ANSYS软件提供的APDL语言对吊杆张拉力进行优化,只要给出模型的成桥吊杆力和任何一组张拉序列,程序即可计算出各张拉工况下的吊杆力的大小,这样能够有效地提高模型计算的工作效率。

| Abstract: | Self-anchored suspension bridge must accomplish the system switch by tensioning suspenders. Generally, suspender force is confirmed through manual and iterative calculation, there will be too much work to do. The paper puts forward a way which can optimize suspender forces by APDL based on ANSYS. In this way, the program can figure out values of suspender forces in sorts of conditions as long as suspender forces of the completed bridge and any set of sequence of tensioning are input. It can improve the work efficiency of calculation effectively. |
