硫酸盐腐蚀后混凝土受弯构件力学性能研究

Research on mechanics property of reinforced concrete bending members after corrosion of sulphate

通过对受硫酸盐溶液腐蚀的钢筋混凝土受弯构件进行试验研究,分析了其在经受硫酸盐短期和长期腐蚀后力学性能的变化规律,并提出了长期腐蚀后钢筋混凝土受弯构件的承载力折减模式。

Based upon tests on reinforced concrete beams after corrosion of sulphate, analyzed the changing discipline of mechanics property after short-term and long-term corrosion of sulphate, and proposed the calculating methods of bending bearing capacity for the reinforced concrete beams under long-term sulphate attack.
