摘要
依既有结构的技术使用寿命密度函数服从截尾分布,建立了既有结构的条件可靠度和失效率函数,从期望效益与其望经济风险的优化分析着手,提出了一种既有结构剩余技术寿命的预测方法。
The technical sevice life of structures is a random variable,and the residual technical service life is an optimum result of economic benefit and hazard.Based on that the density distribution function of technical service life about existing structures obeys blocking tail distribution,a conditional reliability and a hazard rate function of existing structures are established in this paper.On the optimum analysis for expectant economic benefit and economic hazard,a calculation method about residual technical service life of existing structures is proposed.
