橡胶混凝土砖填充墙的抗震性能

采用有限元方法分析了橡胶混凝土砖填充墙-框架体系的滞回性能.橡胶砖的滞回曲线饱满，其耗能面积比粘土砖大， 耗能系数是粘土砖结构的1.17倍.橡胶砖结构刚度较小，整体结构刚度低于粘土砖结构.橡胶混凝土砖结构的延性优于粘土砖结构，其结构体系具有良好的延性，能提高结构的抗震性能. 橡胶砖结构具有良好的吸耗能能力，保证结构在地震作用下具有良好的变形能力.

Seismic capability of the infilled wall with rubber concrete brick

The hysteretic performance of rubber concrete brick infilled wall-frame system was studied by using finite element analysis. Rubber brick hysteretic curve is full, and the energy dissipation area is more than the clay brick. The energy dissipation coefficient is 1.17 times of clay brick wall. Because of low stiffness, the stiffness of the rubber brick infilled wall-frame system is less than of clay brick one. The ductility of rubber brick concrete infilled wall is better than of clay brick. The plastic deformation of structure was reduced, and the system has good ductility. Rubber concrete brick infilled wall has good absorption energy dissipation capacity and ensures that the structure has good deformation capability under seismic action.
