钢筋混凝土梁在冻融锈蚀环境下的劣化规律研究

Study on the degradation law of reinforced concrete beams under freeze-thaw and corrosion

对4组试件进行冻融锈蚀环境下的试验研究,探讨了钢筋混凝土梁在冻融、锈蚀、先冻融后锈蚀、先锈蚀后冻融环境下的极限承载力和极限挠度的劣化程度,结合试验数据对钢筋混凝土梁在冻融锈蚀环境下的劣化规律做了进一步的分析,并对今后的研究方向提出了建议。

The degradation level of ultimate strength and limit deflection of reinforced concrete beams is studied through 4 groups of specimens in the environment of the freeze-thaw,corrosion,corrosion after freeze-thaw first and freeze-thaw after corrosion first.A further analysis is made on the reinforced concrete beams in the environment of the freeze-thaw and corrosion with the test data.Finally,some advice is given for future research.
