| 摘 要： | 依据现行抗震设计规范,运用三维有限元软件ANSYS对某25层大底盘非对称双塔连体结构进行了时程法地震反应分析,得到结构的自振特性和地震响应,并与未设连体的双塔结构的结果进行了比较.结果表明增设连体后双塔的扭转振型更加丰富,且运动和变形得到了统一和协调. |

| Abstract: | According to the present Code for Seismic Design of Buildings,a time history method of seismic analysis for a 25-story unsymmetrical double-tower connecting structure,is carried out by using FEA software ANSYS.Its dynamic characteristic and seismic responses are analyzed,and compared with the double-tower structure without connection.The results show that the structure has complex torsional modal and its movement and deformation are harmonized when set the connection. |
| Keywords: | Tall building Double-tower structure Connection Seismic responses Time-history analysis |
