| Abstract: |
Ultimate load carrying capacity is one of important factors for long span arch bridges. In this paper, ultimate load carrying capacity analysis of two long span arch bridges in China is introduced. The first bridge is Taiping Lake Bridge, which is a concrete filled steel tubular (CFST) arch bridge with main span of 336m in Anhui Province. The second bridge is Chaotianmen Bridge, which is a truss bridge with main span of 552m in Chongqing City, and Chaotianmen Bridge will break the world record of arch bridge, which is holding by Lupu Bridge now. The analysis is based on nonlinear finite element method (FEM), and the whole collapse process which passed through several plastic hinges is introduced in detail. Different characteristics of ultimate load carrying capacity about those two types of arch bridges are also compared, which will give some helpful experiences for similar bridges. |
