钢筋混凝土结构基于耐久性劣化度的可靠性分析
Reliability analysis of reinforced concrete structure based on durability and deterioration grade
摘要
Abstract
The durability deficiency of a structure can cause its performance deterioration and lead to lower structural reliability.Based on two deterioration grade models and limit state method established, reliability calculation method for whole service life of concrete structure was suggested using two different deterioration grades for durability as indexes.Combined with actual engineering examples, the limit state functions were set up with an example of carbonation degradation problem of concrete structure under load and then were analyzed based on the two deterioration grade models by applying reliability theories.The calculation method of structure reliability based on durable deterioration grade was researched in this paper, which provided reference for analyzing the durability of engineering structure in service.The results show that durability of structures and the statistical values of concrete cover thickness and carbonization rate or the amount of steel corrosion are closely related.关键词
