摘    要:由钢筋锈蚀造成的桥梁结构损伤是一种常见的病害形式。不均匀锈蚀通常会造成结构不均匀损伤,这种损伤通常会改变结构的受力形式而使结构处于更加不利状态。本文以桥梁墩柱结构中比较常用的轴压构件和大偏压构件为例对钢筋非均匀锈蚀以后结构的破坏形式和可靠性进行了分析,期望为旧有桥梁结构的可靠性鉴定提供新的分析思路。

关 键 词:桥梁工程  可靠性  钢筋锈蚀  破坏形式

Abstract:It is common that reinforced concrete bridges are damaged with steel corrosion which not only reduces the strength of structures but also changes their failure mode if there exists nonsymmetry corrosion developed to some extent. Nonsymmetry corrosion can translate ductile fracture into brittle failure and translate flexural failure into torque failure, etc. Usually translation of failure mode is ignored, which should result in much more serious conclusions. The main aim of this paper is to present the importance of nonsymmetry corrosion. Components under geometric center compression and large eccentric compression are taken as examples for bridge pier and column structure reliability analysis.
Keywords:Bridge engineering  Reliability  Steel corrosion  Failure mode
