基于abaqus中cohesive element 对钢筋混凝土粘结性能
的研究
摘要：考虑到钢筋与混凝土界面受力的复杂性，基于用来模拟三种裂缝和失效的零厚度界面单元，采用分离式模型，引入内聚力黏结模型，并以文献中的拉拔试验结果为参照，利用abaqus中cohesive element单元建立起钢筋拉拔试验的计算模型。通过与文献中试验结果的比较，结果符合较好，验证了该计算模型的合理性。 关键词：钢筋混凝土粘结；拉拔试验；黏结单元；数值模拟 abstract: considering the steel and concrete of the complexity of the interface stress, based on the three kinds of cracks and used to simulate the failure of the zero thickness interface unit and using the separate model, the introduction of cohesion cohere model, and the literature to pull out tests results as the reference, using abaqus cohesive element in the unit set up reinforced pull out tests of calculation model. through literature and the comparison of the test results, the results are in good conformity, verify the calculation model of rationality.
