摘　　要：本大厦为高位连体大跨度结构,其中连廊结构采用两层钢结构,跨度为40m,此类大跨度结构,往往存在着振动问题,从而影响舒适度,适宜的舒适度有利于人们的工作和学习,本文采用MIADS软件对本工程进行结构模态分析,研究了人群荷载对连廊的影响。研究表明,没有布置减振装置时,人行荷载将引起较大的振动,合理布置TMD之后,将有效减小连廊的振动。The project is a high-position connected structure, in which the corridor structure is a two-story steel structure with a span of 40 meters.This kind of long-span structure office structure often has vibration problems, which affects the comfort degree.The appropriate comfort degree is conducive to people’s work and learning.This paper analyzes the structural dynamic characteristics of the project, and studies the load characteristics of the pedestrian load.According to the analysis results, the energy dissipation design is carried out, and the energy dissipation device is arranged reasonably.
