摘要:
本文探讨了组合拱式管桥载荷效应组合和结构构件抗力统计分析问题,建立了组合拱式管桥结构构件的失效准则,运用一次二阶矩中心点法推导出相应单项可靠指标的计算公式,这些公式可作为组合拱式管桥可靠性分析与设计的参考。
关键词: 管道设计, 组合拱式管桥, 结构力学, 指标, 可靠性
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
