Based on the Different Specifications of Jacking Construction of Continuous Girder Bridge Reliability Analysis

Abstract:

The purpose of this paper is aimed at according to the "highway reinforced concrete and prestressed concrete bridge and culvert design specifications (JTG D62-2004) and (JTJ 023-85) design of jacking construction of continuous girder bridge for reliability analysis. By establishing a finite element model of construction stage and into a bridge stage respectively the reliability index of the typical cross section is analyzed. Aiming at construction stage, by choosing typical cross section of reliability analysis, draw a cross section of reliability index with the change of construction stage. Calculation results show that, according to JTG D62-2004 specification of reliability index calculation results than based on results of calculating the JTJ 023-85 specification. In this paper, the analysis results can provide reference for pushing the construction of the continuous girder bridge design.
