本文的目的是展示根据实验数据评估桥梁动态特性的各种技术的比较研究结果。本文对 2001 年 2 月举行的国际模态分析会议的一次高级会议上提出的工作进行了回顾和综合。世界各地的研究团队受邀参与一项研究，以比较模态分析技术，根据受迫振动、自由振动和环境振动数据评估桥梁的动态特性。瑞士的一座三跨钢筋混凝土桥梁 Z24 桥被选为案例研究。练习的两个目标是比较参与者实验室中通常采用的模态分析技术，以及比较大型土木工程结构的典型激励技术的结果。共有六个研究团队接受了挑战。他们使用的系统识别方法从基本的取峰方法到高级的子空间识别方法。所有团队都比较了至少两种激励类型。 (C) 2003 Elsevier Science Ltd. 保留所有权利。
The purpose of this paper is to present the results of a comparative study of various techniques for evaluating bridge dynamic properties from experimental data. The paper presents a review and synthesis of the work presented in a developed session of the International Modal Analysis Conference of February 2001. Research teams all over the world were invited to participate on a study to compare modal analysis techniques for evaluating the dynamic characteristics of bridges from forced, free and ambient vibration data. The Z24-Bridge, a three-span reinforced concrete bridge in Switzerland, was selected as a case study. The two objectives of the exercise were to compare the modal analysis techniques that are usually employed in the laboratories of the participants and to compare results from typical excitation techniques for large civil engineering structures. A total of six research teams accepted the challenge. The system identification methods that they used ranged from the basic peak-picking method to the advanced subspace identification method. All teams compared at least two excitation types. (C) 2003 Elsevier Science Ltd. All rights reserved.
