摘要
以内蒙古自治区巴彦淖尔市临河区西区非对称三塔连体结构办公楼为例,利用ANSYS有限元软件,分析了主体结构与连廊结构的刚性连接、铰接、滑动连接、隔震支座等连接方式对结构周期、振型等振动特性的影响.结果表明:随着连接的增强,主体结构与连廊结构的相对位移变化减小,低阶振型自振周期明显减小,平扭耦联效应增大.
Taking an offices of asymmetric three-tower connected structures in west part of Linhe District, Bayannur League in Inner Mongolia Autonomous Region as an example, the authors using ANSYS finite element analysis software as the tool, analyzing the effect of different connection ways of joint corridor and towers in the cycle of structure and modal shapes re- sponse, and the connection ways included the models with different connection ways are the structures with a rigid collection or hinged at both ends, sliding connection, isolation bearing between the joint corridor and towers. The results showed that with the augmentation of the connection, relative displacement of the joint corridor and towers change decreased, and the low order mode vibration cycle decreased obviously, the translation-torsion coupling effect increased.
