| Abstract: | Combined with the creep experiment of HPC for the Grand Canal bridge at the Suhuai Expressway the calculation formulas for elastic modulus and creep degree are introduced.The result calculted by the formulas is idential with the tests result.lt is approved that the higher of strength and elastic modulus of HPC, the lower of the creep coefficient, it is helpful for decreasing prestress loss and long term deformation. |
