| Abstract: | This paper analyzes the stress state about four control sections of Lijiaxiang bridge under seven load cases. The finite element space model of the steel-concrete beam linked part of the host-bridge is built. And the various mechanical indexes about the steel-concrete beam linked part is analyzed. According to the comprehensive analysis, the bridge span structure is in flexible working state under the design loads,and the stiffness and the load carrying capacity of the structure meet the requirements of design. The steel-concrete beam linked part is under the reasonable stress state and various mechanical indexes meet the requirements of corresponding standard. |
