Abstract:

This paper discusses the problems on the loading response combination of combined-arched pipe bridge and the statistical analysis of the component resistance of the structure, sets up the failure criteria for the components of the structure, and derives the formulas to be used for calculating the itemized reliability indices of the pipe bridge by using the centre-point method of the first-order second-moment theory. They formulas can be used as the basis of reliability analysis and the design of combined-arched pipe bridge.

Key words: Pipe line design, Combined-arched pipe bridge, Structural mechanics, Index, Reliability
