摘　　要：为了了解用再生砖砌成的砖混结构住宅房屋的动力特性和抗震性能,对一个四层、1/3缩尺的再生砖砌体砖混结构住宅房屋模型进行多种工况的振动台试验研究和分析。观察记录模型在不同地震和烈度下的破坏机理和形式,以及测得各楼层相对底层的最大位移和位移时程曲线,评估结构的变形能力和抗震性能。试验结果表明,再生砖砌体砖混结构模型具有良好的抗震性能,能够达到砖混结构的"小震不坏,中震可修,大震不倒"的要求。建议对房屋设置抗震缝,增强结构的变形能力和抗震强度。研究成果对进一步了解再生砖结构体系的动力特性和抗震性能具有重要的意义,可为该结构抗震设计提供相关依据和参考。A series of shaking table tests for four floor brickconcrete 1/3 scale model houses with the construction waste bricks were carried out to further understand its dynamic characteristics and seismic performances. Structures＇ failure mechanism synthetically under different levels o f earthquakes can be observed, and each floor relative bottom maximum displacement and the displacement-time curve can also be measured to estimate the deformability and earthquake resistant behaviour of the structure. The results showed that： the brickconcrete model with the construction waste bricks has a good seismic performance, and can reach the requirements ＂ minor earthquake ,the earthquake can repair the earthquake does not fail＂ of the brick mixes a structure. It is suggested that the house set structure seam to enhance the distortion of the structure and the capability and shock strength. The research results to further understand regeneration brick structure of the system dynamic characteristics and seismic performance have the vital significance, and for the seismic design of structures to provide relevant basis and reference.
