盐蚀钢筋混凝土梁抗弯承载力试验分析

将10根钢筋混凝土梁在含盐环境中侵蚀后进行抗弯承载力试验，通过对不同腐蚀程度的梁在简支情况下试压的结果进行对比分析，研究了钢筋混凝土梁在遭受腐蚀的不同时间段内梁的抗弯承载力的变化情况．认为盐蚀钢筋混凝土梁与普通钢筋混凝土梁正截面破坏特征基本相同；初始强度不同的试件耐受腐蚀的程度不同，影响钢筋程度也不同，进而影响试件的宏观性能；钢筋混凝土梁抗弯承载力随盐蚀时间的延长而呈波浪状发展．

The Experiment and Analysis of Bending Capacity to Reinforced Concrete Beams Corroded by Salt

By way of the bending capacity test on 10 pieces of reinforced concrete(RC)1 beams pressurized on simply supported,the comparing results of the beams suffered salt corrosion in varying degrees were studied ,and the changes of the bending capacity for the RC beams during different time periods for suffering corrosion were investigated.The law was as follows:The characterics of upright section failure for RC beams attacked by salt are about the same as that for ordinary RC beam;The resistivity to salt corrosion for the concrete specimens with various initial strength,the influence degrees to the reinforced by salt and next step the macroscopic performance of these beams are different;Along with the extension of the time for salt the bending capacity for upright section of RC beams varys wave upon wave.
