| Abstract: |
| The deformation parameters test of 55MPa high-strength concrete of main beam at Huangshi highway bridge include: elastic modulus, creep, shrinkage and long - age deformation of bending member. The test results will provide practical basis for deformation supervision of bridge main beam during construction. The test results and values select and revision methods in practice are given. |
| Key words: elastic modulus,creep,shrinkage,deformation,beam,concrete |
