摘要
大跨和高层建筑结构设计考虑的重点是地震作用和风荷载,其要点为设计出能够承受地震动及风致振动效应的结构体系,而振动控制和减隔震技术是建筑结构抵抗地震作用和风载、减小振动响应的有效途径。简要概括了建筑结构抗震设计方法的发展历程,重点介绍了几种阻尼器的基本工作原理及其特点。详细分析了国内重大结构工程中选用不同阻尼器进行抗风减震的典型案例,如云南省林科院办公大楼抗震加固工程、上海中心大厦新型阻尼器,为今后需要采用抗风减震技术的结构工程提供宝贵经验。
The structure of the system to withstand seismic ground motion and wind-induced vibration effect to be design is the key of large-span and high-rise building structure design,and vibration control and anti-seismic technology is the effective ways to resistance to earthquake and wind load,reduce the vibration response of building structural.The development course of seismic design method of building structure was briefly summarized,the basic working principle and characteristics of the damper were introduced,several kinds of typical cases with the wind vibration damper were analyzed in detail,provide valuable experience for structure engineering with isolation technology,such as Yunnan Forestry Science Institute office building aseismic reinforcement engineering and Shanghai tower engineering new damper.
