| Abstract: | The experiment on creep and shrinkage of high-performance concrete used in Sutong auxiliary bridge which is a three span prestressed concrete continuous rigid-frame box girder bridge （140 m＋268 m＋140 m）with single cell is introduced. Six commonly-used prediction models for concrete shrinkage and creep are compared with some experimental results. It can provide necessary analytical parameters for the construction. |
