本文讨论了多重调谐质量阻尼器(MTMD)的配置和尺寸,试图改造人行桥的多个关键模式所产生的行人交通的激励。本文提出的简单实用的方法包括使用迭代分析/重新设计类型的程序,收敛到给定的允许加速度水平。一个例子,使用这种方法来改造现有的人行天桥。DOI:10.1061/(ASCE)ST.1943-541X.0000527。(C)2012年美国土木工程师学会。
This paper deals with the allocation and sizing of multiple-tuned mass dampers (MTMDs) in an attempt to retrofit footbridges with multiple critical modes resulting from the excitation of pedestrian traffic. The simple and practical methodology proposed herein includes the use of an iterative analysis/redesign type procedure that converges to a given allowable level of accelerations. An example that uses this methodology to retrofit an existing footbridge is presented. DOI: 10.1061/(ASCE)ST.1943-541X.0000527. (C) 2012 American Society of Civil Engineers.
