摘　　要：本文以某多功能一体化建筑为工程背景,利用SAP2000软件建立数值分析模型,通过分析结构自振特性验证了结构平面布置的规则性。研究了钢桁架连廊与塔楼之间的连接方式、连廊设计位置和数量、塔楼非对称性和建筑底盘高度变化对结构振动特性的影响规律。结果表明,钢桁架连廊的连接方式和建筑底盘高度变化对结构整体刚度影响很小;连廊宜设计在塔楼中间层位置,且在条件允许的情况下可考虑多设一道连廊;在设计中尽可能降低两侧塔楼的高度差异,减小扭转效应。The numerical analysis model was established by SAP2000,and the regularity of the structure layout was verified by analyzing the self-vibration characteristics of the structure.The dissertation studies the influence of the connection mode between the steel truss corridor and the tower,the design position and quantity of the corridor,the asymmetry of the tower and the change of the height of the building chassis on the vibration characteristics of the structure.The results show that the connection mode of the steel truss corridor and the height change of the building chassis have little effect on the overall stiffness of the structure.The corridor should be designed in the middle level of the tower,and an additional corridor may be considered when conditions permit.The height difference between the two towers should be minimized to reduce the torsional effect.
