Reliability analysis of pre-stressed concrete continuous girder bridges using the incremental launching method on Chinese code and BS5400

ByC.H. Lou & F.H. Dong

The bridge, which is a double-parallel pre-stressed concrete post-tensioned continuous girder bridge with dimensions of 30 m + 3 × 40 m + 30 m, is constructed by incremental launching method in the highway, and its total length is 180 m. The length of the center of the side pier and the beam-ends is 0.45 m; in addition, the length of the side span is 29.55 m. The launching nose is 25 m long and the ratio of it to main span is 5/8. The geometry of girder is shown in Figure 1, in which all dimensions are in centimeters.
