STUDY ON DURABILITY OF MODERN PRESTRESSED CONCRETE STRUCTURE IN CARBONATION
-
摘要: 对7根快速碳化试件进行了应力分析,建立了不同应力状态下的碳化深度预测模型,随后从理论上对裂缝状态下的预应力混凝土结构耐久性进行了分析;并根据结构可靠度理论,提出了碳化环境下PC结构耐久性可靠度的分析方法。Abstract: A predicting model on carbonation depth considering the effects of stress is built based on the seven fast-carbonation experiment modules. Then, an analysis from theory is given to the prestressed concrete structure in cracked state. According to the theory of structure reliability, an analysis method of durability of PC structure in carbonation is developed.
