| 摘 要： | 既有结构当前的材料强度是客观上完全确定但具有主观不确定性的未确知量.目前的区间估计法为概率推断方法,并不完全适用于对既有结构当前现实的材料强度的推断.该文针对既有结构的特点,分析了目前区间估计法的缺陷,提出了既有结构当前材料强度的信度推断方法.该法具有良好的理论基础,不仅考虑了测试构件与未测试构件之间的差别,而且能够合...

| Abstract: | The in-site material strength of existing structures is an uncertain quantity which is objectively certain but subjectively uncertain.The current interval estimation method is a probability inference approach,which is not suitable for the estimation of realistic material strength of existing structures.Based on the characteristics of existing structures,the paper analyzes the flaw of interval estimation method and then proposes the belief inference method for the estimation of material strength of existing ... |
