摘要
通过对混凝土结构耐久性极限状态的分析,确定把破损形态作为耐久性极限状态的控制目标.利用现阶段的钢筋锈胀力计算模型,提出了基于破损形态控制的混凝土构件耐久性设计方法,并对其影响因素进行讨论和分析.结果表明:所建立的基于破损形态的混凝土结构耐久性设计方法是合理的.按本方法分析,可以稍微放松对混凝土锈胀裂缝宽度控制的尺度,对结构设计提出了新的控制标准.
According to the analysis of concrete structural durability limit state, failure state was regarded as the limit state control of the durability. On the basis of current splitting force calculation model, a durability design method of structural members is proposed, in which the failure state was obtained and its influence factors were discussed and analyzed. The results show that the design method of concrete components based on failure state control is reasonable and the command scale of the crack caused by corrosion can be widen, which provides the new control standard for the structure design.
