【摘要】 混凝土结构是一个多层次、多因素、多功能、多目标的相互联系、相互制约的系统,具有明显的不确定和非线性特征,是一个复杂的动态系统。根据此特征,提出了利用未确知测度分析法来评估其可靠性的新方法。结合混凝土结构可靠性评估特点,应用未确知测度、置信度的概念,得到的评估结果能够客观全面地反映结构可靠性。通过工程实例分析,将评价结果与实际鉴定结果对比,结果显示此方法简单、准确、实用,是混凝土结构综合评价的一个新途径。更多还原

【Abstract】 The concrete structure is a system of connecting and restricting each other of a multi-level,multi-factor,multi-functional and multi-goal.It has obvious nonlinear characteristics and is a typical dynamic system.According to the characteristics,the unascertained mathematic approach is put forward to assess building construction reliability as a new method.The unascertained measure model and the incredible degree were applied to establish a model of evaluating of structure reliability based on unascertained measuring.Through the analysis of project instances,the appraised results will be compared with the actually determined ones,the result shows this method is simple,accurate,practical and a new way on comprehensives appraisal of the building concrete structure.更多还原
