| 摘 要： | 砖砌体是被广泛应用的建筑材料,大量学者对砖砌体的压缩和拉伸行为特性以及应力-应变关系进行了试验研究。研究发现:砖砌体表现出与混凝土相近的应力-应变关系,为基于混凝土应力-应变关系模型发展砖砌体的应力-应变关系模型提供了基础。对已经提出的几种不同的砖砌体应力-应变关系模型进行了比较,通过比较分析,基于中国混凝土应力-应变关系模型,推荐了可用于估计砖砌体单轴压缩和拉伸载荷下应力-应变曲线的简单分析模型,模型中使用的参数不仅可以很容易地通过实验获得,而且常在规范中被规定使用。

| Abstract: | Brick masonry is widely used as building materials,the uniaxial compressive and tensile characteristics and stress-strain relationships of the brick masonry have been studied by a large number of laboratory tests.It is found that the stress-strain relationships of brick masonry are similar to that of concrete,which provides a basis for developing the stress-strain relationship model of brick masonry based on that of concrete.In this study,several different stress-strain relationships of the brick masonry are compared.By the comparison and analysis,a brick masonrystress-strain relationship model under the uniaxial compression and tensile loads is recommended based on the Chinese concrete stress-strain relationship model,and the parameters used in the model are not only easily obtained by tests,but also are often specified in the code. |
