| 摘 要： | 为了研究钢-混凝土混合结构连接方式对抗震性能地影响，运用Canny99结构计算程序，根据不同结构构件采用不同的单元模型，对同一高层钢-混凝土混合结构的两种连接方式进行了三维弹塑性时程分析，探讨了两种连接方式对混合结构抗震性能的影响机理．刚性连接时，钢框架柱主要是依赖轴力的增加来承担部分水平地震力；铰性连接时，钢框架柱主要依赖柱剪力的增加来承担部分水平地震力．研究结果表明混合结构采用刚性连接方式具有较优的抗震性能． |
| 关 键 词： | 混合结构 弹塑性时程分析 连接方式 抗震性能 |

| Abstract: | In order to study the effect of connected forms of steel-concrete mixed structure on anti-seismic performance, by means of Canny 99 structural computing program and different unit models, 3D elasticity-plastic time-history analysis was performed for the steel-concrete mixed structure's two connected forms of the same high story. The effect of two connected forms on mixed structure's anti-seismic performance was discussed: for the rigidity connection, the horizontal earthquake load is borne by increasing axial force of the steal frame columns; for the hinge connection, it is borne by increasing shearing force of the steel frame columns. The results show that the rigid connection has good anti-seismic performance. |
| Keywords: | mixed structure elasticity-plastic time-history analysis connection forms anti-seismic performance |
