摘要
为了研究再生砖砌体砖混结构房屋的抗震性能,采用Taft地震波对一个用再生砖砌成的四层、1/3缩尺比例的房屋模型进行振动台试验,观察记录了在不同强度和烈度下结构的地震反应和破坏机理,并测得各测点加速度反应的最大值、各楼层相对底层的最大位移和位移时程曲线。试验结果表明,用再生砖砌成的房屋经合理的设计可满足砖混结构"小震不坏,中震可修,大震不倒"的要求,具有良好的抗震性能,并建议在结构承重墙体内设置水平配筋,以减轻墙体的脆性,增加其延性,进而提高该结构的抗震性能。
In order to study the seismic performance of brick structure building with recycled bricks, a series of sha king table tests for four storey brick-concrete 1/3 scale model houses with construction waste bricks were carried out. Under different strength and intensity, the seismic response and damage mechanism of the structure is observed and re- corded. The maximum acceleration response of each measure point, the maximum displacement of relative bottom for each storey and displacement time-history curves are measured. The experimental results show that the recycled brick house by the reasonable design can meet the brick structure＇ requirements of not damaging for mall earthquakes, repai- ring for middle earthquakes and not collapsing for strong earthquakes, which has good seismic performance. It is sugges ted that horizontal reinforcements are set in the structure of long-bearing wall to reduce the brittle walls and increase its ductility, and improves the seismic performance of the structure.
