腐蚀环境下混凝土结构疲劳性能研究综述

Study of fatigue performance for corroded concrete structures

混凝土结构是应用非常广泛的一种结构形式 ,反复荷载作用下混凝土结构的疲劳问题正越来越受到人们的重视 .当结构处于腐蚀环境中时 ,由于腐蚀介质的侵蚀 ,结构疲劳性能的降低要比静态性能的明显 .

Concrete structures are widely used,the problems of concrete structures under repeated loadings are more and more important.The fatigue performances of reinforced concrete structure are deteriorated severely as the resultof corrosion of the steel bars.The corrosion fatigue problems thatare to be studied of concrete structures are analyzed in this paper.
