钢筋混凝土界面问题分析模型

Analysis model for reinforced concrete interface problem

钢筋与混凝土主要通过界面黏结作用来共同承受荷载,在界面上的受力属于不连续介质的力学问题.应用解决不连续介质力学问题的界面应力元法建立交界面的分析模型,对拔出试验和拉伸试验进行了数值模拟,数值模拟计算结果与试验结果接近.

Reinforcement and concrete bear loads together by bonding on their interfaces, and interface stress is a discontinuous medium-rclated mechanical problem. An interface analysis model was established based on the interface stress element method for discontinuous medium mechanical problem to simulate the pull-out tests and tensile tests, and the calculated results are in good agreement with those of experiments.
