基于TMD的机场登机桥舒适度研究

ANALYSIS OF FLOOR COMFORT AND APPLICATION OF TMD FOR A STEEL FRAME FLOOR STRUCTURE IN TERMINAL

调谐质量阻尼器(TMD)是目前高层建筑和大跨度结构振动控制中应用最早的被动装置之一。根据调谐质量阻尼器的参数核算,将附加质量比控制在结构允许范围,结构总阻尼比提高至预定值,对其结果进行进一步分析可解决按传统方法直接进行抗震计算遇到的舒适度问题。采用振动控制设计增强了本工程的结构安全'性,提升了振动过程中的舒适度,对建筑本身和客户体验有着积极意义。以西南某机场项目为基础进行TMD舒适度的计算,结果表明TMD很好地解决了航站楼登机桥的舒适度问题。

TMD is one of the earliest passive devices used in vibration control of high-rise buildings and long-span structures.According to the calculation of the parameters of the tuned mass damper,the additional mass ratio is controlled within the allowable range of the structure,and the total damping ratio of the structure is increased to a predetermined value.Further analysis of the results can solve the comfort problem in the direct seismic calculation by the traditional method.The vibration control design enhances the structural safety of the project,improves the comfort level in the vibration process,and is of positive significance to the building itself and the customer experience.In this paper,TMD comfort is calculated on the basis of an airport project in southwest China,and the results show that TMD solves the comfort problem of terminal boarding bridge well.
