摘要
运用有限元分析软件ANSYS对某25层大底盘双塔连体结构进行了模态分析,并将结果与未设连体及不同高度处设置连体的双塔结构进行对比.结果表明,设置连体后双塔结构的高阶自振频率显著增大,高阶振型中扭转振型更加突出.
ANSYS program is used foramodal analysis of connected twin-tower structures with an enlarged base in order to compare that of the twin-tower structures without connection and the twin-tower structures with connection at different positions.The results show that the high frequencies of the twin-tower structures with connection increase significantly,the torsion mode of the twin-tower structures became more obvious in the high order modes.
