对称双塔连体结构的动力特性分析

Analysis of Dynamic Characteristics of Symmetrical Connection Structure with Twin-towers and Large Chassis

依据现行抗震设计规范,运用三维有限元软件ANSYS,对某33层大底盘对称双塔连体结构进行动力特性分析。结果与未设连体的双塔结构进行比较,对不同高度设置连体进行讨论。结果表明,增设连体后双塔的自振频率提高,扭转振型更加丰富,且运动和变形得到了统一和协调。

Under the current seismic design code, ANSYS software of three - dimensional to make a modal analysis of a 33 - storey symmetrical twin - towers connection structure and the finite element is used dynamic properties of the structure. The results of different location connections and non - connection twin towers structure are each other. The analytical results show that the reverse vibration modes after the addition of the twin towers abundant, and the movement and deformation become unified and coordinated.
