| 摘 要： | 再生骨料替代率为75%,再生混凝土多孔砖强度等级接近MU10.考察再生混凝土多孔砖墙体的受压性能,通过对2片再生混凝土多孔砖墙体进行轴心竖向荷载作用下的试验研究.结果表明,再生混凝土多孔砖墙体在竖向荷载作用下的破环全过程和普通混凝七多孔砖墙体基本相似,受力全过程分为3个阶段:弹性阶段、裂缝发展阶段以及破坏阶段.偏于安全考虑,再生混凝土多孔砖砌体的轴心受压承载力可参照GB 50003-2010<砌体结构设计规范>(征求意见稿)中有关砌体受压承载力计算公式进行计算.

| Abstract: | The strength grade of recycled concrete perforated brick wall is close to MU10 when the replacement ratio of recycled aggregate is 75%.The compressive performance of the recycled concrete perforated brick wall was investigated by the experimental study on two recycled concrete perforated brick walls under the function of axial vertical loading.The results show that the compression failure process of recycled concrete perforated brick wall is similar to that of ordinary concrete brick walls,which was divided... |
