| 摘 要： | 提出了带竖向构造钢筋再生混凝土砖砌体结构,进行了2个两层再生混凝土砖砌体房屋结构1/2缩尺模型的模拟地震振动台试验研究,2个结构模型的墙体厚度均为120 mm,一层设有门洞和窗洞,二层设有窗洞。2个模型中,1个为带竖向构造钢筋再生混凝土砖砌体房屋,1个为普通无竖向构造钢筋再生混凝土砖砌体房屋。试验中输入El Centro地震动,测试分析了台面加速度反应、一层和二层顶板加速度反应、结构层间位移反应以及各阶段结构损伤与破坏特征等。研究表明:带竖向构造钢筋再生混凝土砖砌体房屋比普通再生混凝土砖砌体房屋的破坏程度轻,墙体裂缝位置相对错动小,抗震性能显著提高;带竖向构造钢筋再生混凝土砖砌体房屋可用于地震区村镇建筑。

| Abstract: | The recycled aggregate concrete(RAC) brick masonry structure with vertical constructional reinforcements is proposed in this paper.The experimental study of two RAC brick masonry buildings with two floors is carried out by shaking table test.The two test models have the same wall thickness 120 mm.The door and windows are set on the first floor,and the windows are set on the second floor.The difference between the two models is one with vertical constructional reinforcements,and the other without.The El Centro earthquake ground motion was input to the models during test.The acceleration on the shaking table,the first floor and the second floor,the displacement between adjacent floors,the structural damage and failure characteristics during every stages are tested and analyzed.The results show that: compared to the normal RAC brick masonry building,the building with vertical constructional reinforcements has slighter damage and smaller relative displacement between RAC bricks and shows better seismic performance.The buildings with vertical construction reinforcement may be used in the seismic rural areas. |
