Abstract

The object of this paper analyzes the reliability level of pre-stressed concrete continuous girder bridges designed with the Chinese codes including the code for design of highway reinforced concrete and pre-stressed concrete bridges and culverts of AASHTO LRFD-2012 and JTG D60-2015 using cantilever construction method. Typical cross-sections used in the example bridge are considered at service stage. Load and resistance parameters are treated as random variables. The statistical parameters are based on the available literature, test data and survey results. Reliability indices are calculated by iterations using the first-order second-moment method. The calculated results indicate that the reliability indices on the code of AASHTO LRFD-2012 vary considerably to the code of JTG D60-2015. And it could provide the references for the reinforcement of old bridges and the design of new bridges using the cantilever construction.
