摘　　要：目的研究不同填充墙分布形式,不同填充材料及不同填充率情况下填充墙-框架结构在地震下的工作性能.方法采用时程分析法,分析在地震作用下,采用不同填充墙布置形式的黏土砖填充墙、粉煤灰砖填充墙和橡胶混凝土砖填充墙的墙-框架体系的抗震性能.结果采用相同填充墙布置形式,不同填充墙填充材料时,橡胶混凝土砖填充墙-框架结构最大水平位移最小,位移角最小,扭转角最小;在不同填充率下橡胶混凝土砖填充墙-框架结构均能减小层间扭转角;橡胶砖填充墙-框架的刚度介于纯框架与黏土砖墙框架之间,能较好地满足结构的正常使用条件.结论橡胶混凝土砖结构墙体布置灵活,在地震发生时能较好地吸收和消耗地震波能量,橡胶混凝土砖的应用可以有效提高填充墙-框架结构的抗震性能.The purpose of the paper is to study the seismic behavior of the wall-frame structure with different infilled forms, materials and rates. Using the time history analysis method, seismic behaviors of the wall-frame structure infilled with the different materials, such as clay brick, fly ash brick and rubber concrete brick and different infilled forms were analyzed. It is found that with the same decorate form, compared with other infilled materials, the maximal horizontal displacement of the wall-frame structure infilled with rubber concrete brick is minimum. The displacement angle and the torsion angle are also minimum. The layer twist angle can be reduced by the different rate of rubber concrete brick. Its stiffness is between the pure frame and the clay brick infilled frame. Conclusion is that the wall-frame infilled with rubber concrete brick can be arranged flexibly. It can absorb and consume the seismic wave energy effectively. Application of rubber concrete brick can effectively improve the seismic behavior of the infilled wall-frame structure.
