摘要(Abstract):

通过逆向加载的方式对混凝土多孔砖砌体的应力-应变曲线进行试验研究。分析了混凝土多孔砖砌体受压过程不同阶段的特征,并与普通砖砌体进行比较。试验表明,混凝土多孔砖砌体呈现出较普通砖砌体更为明显的脆性特征。提出了反映砌体受压应力-应变全曲线的本构关系,该本构关系包含了混凝土多孔砖砌体受压试验所表现出的几乎全部特征。
The stress-strain curve of concrete porous brick masonry is studied by the way of the reverse load.The characteristics of concrete porous brick masonry in different stages are analyzed,and it is compared with the ordinary brick masonry.The experimental results indicated that concrete porous brick masonry has more significantly brittle characteristics than ordinary brick masonry.The compressive stress-strain curve is advanced,and the constitutive relationship shows almost all the characteristics in the concrete porous brick masonry compression tests.
