基于可靠度的结构风险损失研究

Structural Risk Analysis Based on Structure Reliability Index

以总费用最小为目标 ,研究结构可靠度。通过对轴心受压构件的分析 ,给出风险损失与结构可靠指标之间的定量关系。分析结果表明风险损失与结构可靠指标之间大致上呈指数关系。

The structure reliability is analyzed with the object that the cost is minimum. Analyzing an axially loaded column derives the relation between risk cost and structure reliability index. The relation coincides with exponential curve.
