【摘要】 钢筋腐蚀是影响钢筋混凝土结构耐久性的首要因素,国内外对受腐蚀钢筋混凝土结构的性能已经做了一些研究。本文简介了这方面研究的现状,其中包括研究的方法、受腐蚀钢筋混凝土结构的抗弯性能、抗剪性能、钢筋和混凝土的粘结性能、使用荷载作用下的性能和动力性能,并对需要重点加强研究的方面提出了建议。指出目前对受腐蚀钢筋混凝土结构抗剪性能和动力性能的研究仍然极少,特别是对受腐蚀钢筋混凝土结构疲劳性能的研究几乎还是空白,因此建议今后加强这些方面的研究。更多还原

【Abstract】 Durability problem of steel reinforced concrete structures is drawing more and more attention. Corrosion of reinforcing bars is the most important factor influencing the durability of steel reinforced concrete structures. Performance of corroding reinforced concrete structures has been studied home and abroad recently. In this paper the overview of the studies is presented ,including research technique, bending resistance performance, shearing resistance performance, bonding performance of steel and concrete, performance under service load and dynamic performance. And some advice on the future studies is given. Studies on shearing resistance performance and dynamic performance of corroding steel reinforced concrete structures are still limited. And studies on fatigue performance of corroding steel reinforced concrete structures are almost blank. Therefore, studies on shearing resistance performance and dynamic performance especially fatigue performance of corroding steel reinforced concrete structures should be emphasized in the future.更多还原
