Parametric Modeling Of Cable-stayed Bridge Based On Secondary Development Of ANSYS

ANSYS is one of the most famous finite element software, and it includes strong solver, preprocessor and postprocessor. ANSYS can solve complex and complicated engineering problem. However, as a general finite element software, ANSYS is not very well in specialized field. And, bridges have many specific characteristics. So, developing a specialized program module, which can be applied in the structural analysis of bridges in second-development environments provided by ANSYS, has become a impending need in bridges analysis. On the basis of the finite element analysis summarization of structural analysis of Cable-stayed bridge, this paper used APDL, UIDL, UPFS and VC to develop a specialized program module that can be applied in the structural analysis of Cable-stayed bridges. The program module can set up Cable-stayed bridges model automatically based on the inputed parameter. I analyzed a Cable-stayed bridge built by this program module, and the result showed that this specialized program module is correct and practicable. I also explored and summarized basic methods and procedures. All of these can provide benefits for ANSYS second-development work in the future.
