Vertical Crack Moment Test Research on Prestressed Concrete Hollow Slab due to Repeated Load

Abstract:

Prestressed concrete hollow slab bridge is widely applied in the highway bridge in our country, this paper shows that the crack moment decreases when loading time increases through the test of 30 m span real bridge under plate repeatedly loading, and get the calculation formula of crack moment again. The discipline between the crack width with loading process is also explored the conclusion is helpful to understand load cracking behavior under repeatedly loading and damage accumulation and performance of bridges.
