Reliability Analysis of Pre-Stressed Concrete Continuous Girders Bridge Using Incremental Launching Method on Different Codes

Abstract

The object of this paper analyzes the reliability level of pre-stressed concrete continuous girder bridges using incremental launching method during construction stages. Typical cross-sections used in the example bridge are considered at construction and service stages, respectively. The calculated results indicate that the reliability indices on the code of D62-2004 vary considerably to the code of JTJ 023-85. Comparing the reliability indices between the constructions shows the different regularity.
