On the basis of observation of the static strength, rigidity changes and cracking behavior of the model structure at the time the static load on the structure is gradually increased to the service load in the test, the paper also verifies the mechanical properties of the model kernel segments corresponding to those of the actual bridge. The results of test and study suggest that the serviceability performance of the overall model is satisfactory, and the anti-cracking behavior and serviceability of actual bridge section similar to the model section are reliable if the section can be designed as per type A element of partially prestressed concrete.Read More
