Abstract

Abstract

In order to find out how the high-performance concrete(HPC) used in Sutong continuous rigid-frame bridge affects the long-term behavior of bridge,such as long-term deformation,section stress and prestress loss,experimental study on the long-term behavior of the HPC dual cantilever girder is developed under natural environments,which based on the model test of HPC shrinkage and creep.The results show that the HPC can effectively lower the shrinkage and creep,and also reduce the prestress loss,which made the structure deformation be in control.By using finite element software Midas,long-term performance of the cantilever girder is analyzed.The analytic results agree well with the test data.
- high performance concrete,
- cantilever girder,
- shrinkage and creep,
