Simulation Analysis and Process Control of an Arch Bridge for Replacement of Tie Bars
The numerical simulation analysis, by using senior nonlinear finite element analysis software MSC.Marc, was achieved in this paper for the tie-replacing procedures of a steel tube tied-arch filled with concrete. Through this analysis, the control parameters were accurately determined for the installing of new ties and the removing of old ties. Results of numerical analysis ensured the bridge structure stable during the replacement, made the construction of safe and convenient, and played a guiding role in the maintenance and reinforcement. The successful experience could be referenced by other similar projects.
