Stress Analysis and Experimental Verification on Corroded Prestressed Concrete Beam

摘要

The paper presents a finite element analysis and static-load experimental verification on stress performance of corroded prestressed concrete bridge at Bai-Kong bridge of Shijiazhuang City on Beijing-Guangzhou Railway. At first, calculation of the actual bridge is simplified, mesh of the finite element of the bridge model is introduced, including the mesh of the finite element of undamaged bridge and the corroded bridge. For the situation above-mentioned, the finite element calculation result of the actual bridge is also presented in this paper. The graphic of the static load on the actual bridge and the testing spots distribution are described in this paper. Finally, the contrast between the static test result and the finite element calculation result is presented in this paper too.
