| Abstract: | As to the cracking problems that frequently occur on the long span Prestressed Concrete(PC) bridges, the parametrization solid modeling is implemented for long span PC bridges by secondary development on ANSYS. Some key technological problems in the spatial simulation of long span PC bridges are solved, such as parametrization modeling of box girders with various sections, parametrization modeling of complex prestressed tendons, high precision element meshing, construction procedure simulation, and so on. And then a complete set of technological process of bridge spatial analysis is proposed based on ANSYS. The construction procedure simulation analysis on a long span PC bridge using the technological route proves the feasibility of the technology. |
