| Abstract: |
The Taiping Lake Bridge is a concrete filled steel tubular (CFST) arch bridge located in Anhui, China. In order to ensure the safety and durability performance of this bridge for construction and operation stages, finite element method is used to optimize the detailed design of arch spring, as well as the construction plan. Ultimate Load Carrying Capacity (ULCC) is also analyzed to obtain the real collapse process of this bridge. The results show that the weak sections of Taiping Lake Bridge are always at the vault and the 1/8 sections during the symmetric loading processes. The ultimate load carrying capacity is determined by these key sections. |
