振动控制在奥林匹克会议中心工程中的应用研究

Adoption of Structural Vibration Control Method in Project of Beijing Olympic Convention Center

北京奥林匹克会议中心是2008年北京奥运会的一项重要的基础设施,长期展示厅位于奥林匹克会议中心的东侧,分为北侧和南侧两个展厅。由于长期展示厅为单跨框架,且结构层高和平面布置分布不均匀,按常规设计方法进行抗震设计将导致结构构件截面过大,影响使用功能,增加造价,同时其抗震性能也难以令人满意。在长期展示厅的设计过程中,通过仔细研究和合理设计,通过结构振动控制技术改变结构的动力特性来消弱结构的动力响应,大幅度增强了结构抗震性能,同时提高了性价比。

Beijing olympic convention center is one of the most important buildings of Beijing 2008 olympic game, and the exhibition street is located on the east side of the convention center, which is composed of north exhibition street and the south exhibition street. Since the exhibition street is a single-span frame structure and the story height and plan layout art are not well-distributed, it is difficult for the seismic design using the normal design method. The method of structure vibration control is adopted in the design of the exhibition street, and structural seismic performauce is obviously enhanced.
