| 摘 要： | 为研究高层屈曲约束钢板墙-混凝土框架结构的抗震性能，分别设计了一个10层钢筋混凝土框架结构和屈曲约束钢板墙-混凝土框架结构模型，进行了地震作用下动力非线性分析。结果表明：屈曲约束钢板墙可显著减小高层钢筋混凝土框架结构在地震作用下的层间位移，同时在罕遇地震作用下框架中塑性铰的数量也有大幅减少，表现出良好的抗震性能。在此基础上，综合规范对框架结构和框架-抗震墙结构抗震等级和柱轴压比限值的规定，并结合屈曲约束钢板墙-混凝土框架结构的受力特点，提出了高层屈曲约束钢板墙-混凝土框架结构的抗震设计建议。建议屈曲约束钢板墙的边缘构件按框架结构确定抗震等级和柱的轴压比限值，其他框架部分根据其承担的地震倾覆力矩比例大小，按框架结构或框架-抗震墙结构确定抗震等级和柱的轴压比限值。

| Abstract: | The seismic performance of high-rise reinforced concrete frame with buckling restrained steel plate shear walls (BRW-RC frame) was studied by dynamic nonlinear analyses of a ten-story RC frame structure and a BRW-RC frame structure under actual ground motions. The results show that the BRW has good seismic performance, since the inter-story displacement and the number of plastic hinges in the high-rise RC frame structure are significantly reduced. Based on the analysis results, the seismic design recommendations for high-rise BRW-RC frame structure are presented combining the structural loading characteristics and the design code on seismic grade and allowable axial load ratio of RC frame structures and RC frame shear wall structures. It is suggested that the seismic grade and the allowable axial load ratio of column for boundary elements of BRWs can be determined according to the RC frame structures. The seismic grade and the allowable axial load ratio of column for other frame columns and beams can be determined according to RC frame structures or RC frame shear wall structures based on the ratio of the earthquake overturning moment. |
