| 摘 要： | 从普通砖砌体的受压试验结果出发,借鉴混凝土本构模型,全面描述了普通砖砌体受压的本构关系。同时采用5次多项式的数学模型,用一条曲线反映普通砖砌体受压的应力-应变全过程,对比结果表明该模型是可行的,能满足工程计算和有限元分析的要求。

| Abstract: | The stress-strain curve of common brick masonry in compression is completely described based on compress test results of literature and constitutive relationship of concrete.At the same time,a mathematic model of 5 degrees polynomial is used,and the whole process of common brick masonry in compression is described by one smooth curve.The results of contrast indicate that the proposed model is feasible and meets the request of engineering calculation and finite element analysis. |
