摘要
纤维与混凝土之间的粘结直接影响纤维对混凝土的增强、增韧和阻裂效果。分析纤维与混凝土界面破坏的过程,提出几种简化的粘结—滑移模型,采用弹簧粘结单元模拟纤维与混凝土之间的粘结—滑移过程,讨论模型参数的确定方法,将模型的计算结果与试验结果进行对比,检验简化模型的合理性。
The binding between fiber and concrete has direct influence of fiber on reinforcement, toughening and anti-cracking of concrete. The procedure of damage of the interface of fiber and concrete has been analyzed and brought forward several simplified models of binding-slippage, adopting spring binding unit to simulate the procedure of binding-slippage between fiber and concrete, discussed the method to determine parameters of the model, made comparison between calculation result of the model and test result to prove the rationality of simplified model.
