摘　　要：混凝土开裂问题和钢筋-混凝土相互作用问题,一直是钢筋混凝土结构研究的热点。应用混凝土塑性损伤开裂模型,引入双弹簧单元来模拟钢筋-混凝土的粘结滑移作用,对Satish C Jain试验的钢筋混凝土板进行数值模拟,并将模拟结果与试验结果作了对比。对比分析结果验证了采用粘结滑移单元与混凝土塑性损伤模型相结合的方法,能够较好地处理混凝土开裂和钢筋混凝土相互作用问题。It is still research focus that the problems of the cracking of concrete and the interaction between concrete and steel bar are still focus for the study on the reinforced concrete structure. The plastic damage cracking model of concrete was used to stimulate the reinforced concrete slab in Satish C Jain experiment by the introduction of the double spring element for stimulating the bond slip interaction between steel bar and concrete. The stimulation results and the test results were compared. The comparison results showed the method of the combination of bond-slip element with concrete plastic damage model can treat the interaction of the cracking of concrete and the reinforced concrete.
