Paper Title:
Study on Bearing Capacity Assessment of Prefabricated RC Slab Bridges
  Abstract

The concept of frequency coefficient is built up based on theory,the formula between frequency coefficient and strain coefficient is established, and it was revised by the regression relational expression on the base of statistics results of 173 samples. The rational range of frequency coefficient was built by regression equation based on the confirmed range of strain coefficient, the frequency coefficient is regarded as a parameter to evaluate the bearing capacity of bridge structure, and its validity and rationality was proved by real project. The results shows that the structure is secure and with some safety margin when the frequency coefficient is greater than 1.111, the structure is dangerous when the frequency coefficient is less than 1.079, and the bearing capacity needs to be evaluated further when the coefficient is between1.111 and 1.079.
