RESEARCH OF THE DEFORMATION ANALYSIS OF THE CONCRETE CREEP AND SHRINKAGE FOR LONG SPAN PC CABLE-STAYED BRIDGE

摘要

In this paper, the method to collect data of static deformation is discussed and the technique of error elimination such as temperature influence is researched with the example of Jinzhou Yangtze River Highway Bridge (a PC cable-stayed bridge with a main span of 500m). The model and the values of shrinkage and creep parameters in bridges design code are identified by comparing the difference between theoretical and actual deformation. The result of analysis would be useful and instructive for other large scale PC bridges both in design and in construction.
