| 中文摘要: |
| 对平面不规则大底盘单塔楼进行隔震分析，分别将层间隔震支座及基础隔震支座应用于此类结构，分别建立层间隔震及基础隔震以及传统的抗震结构模型，利用有限元软件SAP2000对某单塔楼结构在罕遇地震作用下进行动力时程分析。通过楼层剪力，层间位移以及楼层加速度对比，表明采用隔震装置结构的减震效果明显，同时表明由结构平面布置不规则所导致的扭转效应引起我们高度重视。 |

| On plane irregular large chassis single tower isolation analysis, the model is applied in this structure by using story isolation bearing and base isolation bearing respectively. By using of structural finite element analysis software SAP2000,to establish the story isolation and the base isolation and traditional anti-seismic structure model ,which has a single tower structure under severe earthquake, respectively. That layer between the displacement and acceleration floor by floor shear contrast shows obvious damping effect under vibration isolation device structure .At the same time the structural layout of irregular torsion effect cause must be paid great attention to our analysis. |
