冻融循环作用后钢管混凝土界面黏结滑移本构模型研究

Jianzhu Gangjiegou Jinzhan
在北方寒冷地区，钢管混凝土结构因冻融作用侵蚀而造成钢管开裂以及钢管混凝土结构力学性能劣化从而导致结构破坏的事故时有发生。针对冻融侵蚀后钢管混凝土界面黏结性能问题，制作了钢管混凝土推出试件，考虑冻融循环次数、混凝土强度、钢管径厚比等不同参数，进行冻融试验和推出试验，分析了界面黏结力的分布规律和影响因素，研究了冻融循环作用后钢管混凝土界面黏结滑移本构关系，确定了界面平均黏结强度以及峰值黏结强度、残余黏结强度特征值。结果表明，随着冻融循环次数的增加，界面平均黏结强度减小，极限荷载对应的滑移逐渐增大 ...
