混凝土本构关系的边界面模型的讨论

Discussion about a Bounding Surface Model for the Consitutive Relationship of Concrete

边界面模型是目前少有的几个能描述混凝土在复杂的三轴循环荷载作用下性能的本构模型之一，它具有相对简单、应用方便的优点．为了验证该模型，本文根据现有的边界面模型编制了计算机程序．通过计算结果与实验结果的比较，发现了现有的混凝土边界面模型的一些不足之处．

The bounding surface model is one of the models for concrete capable of describing the complex multiaxial cyclic behaviour, and proved to bee more simple and convenientto use.In order to Check this model, a computer programe based on this model was made.Comparisons of model predictions with experimental data under various loading conditions are showed and some defects about the model are found.
