摘要

广州亚运会综合博物馆是2010年广州亚运会的永久性建筑之一，碗状主体为钢结构，最大悬臂长度超过30米。该结构的固有频率较低，因此它往往会受到人们同步行走和共振放大的刺激，这将影响其使用性能。对这座历史博物馆进行了大量的分析和现场测试，使用调谐质量阻尼器（TMDs）来减少人类行走引起的振动。结果表明，TMDs能有效地控制结构的竖向振动，其控制效率可达50%以上。研究结果对类似工程具有明显的借鉴意义。

Human-Induced Vibration Control with TMDs for Guangzhou Asian Games Comprehensive Museum

Guangzhou Asian Games Comprehensive Museum is one of the permanent buildings for the 2010 Guangzhou Asian Games, whose bowl-shaped main body is a steel structure with the largest cantilever length of more than 30 meters. The structure has a low natural frequency, so it tends to be excited by people synchronizing walking with amplification of resonance, which will affect the serviceability. A large amount of analysis and field-tests are performed for this historical museum with tuned mass dampers (TMDs) being used to reduce human walking induced vibration. The results showed that TMDs can control the structure vertical vibration effectively, with the efficiency of over 50%. The research results have obvious significance for similar projects.

期刊介绍： The International Journal of Acoustics and Vibration (IJAV) is the refereed open-access journal of the International Institute of Acoustics and Vibration (IIAV). The IIAV is a non-profit international scientific society founded in 1995. The primary objective of the Institute is to advance the science of acoustics and vibration by creating an international organization that is responsive to the needs of scientists and engineers concerned with acoustics and vibration problems all around the world. Manuscripts of articles, technical notes and letters-to-the-editor should be submitted to the Editor-in-Chief via the on-line submission system. Authors wishing to submit an article need to log in on the IJAV website first. Users logged into the website are able to submit new articles, track the status of their articles already submitted, upload revised articles, responses and/or rebuttals to reviewers, figures, biographies, photographs, copyright transfer agreements, and send comments to the editor. Each time the status of an article submitted changes, the author will also be notified automatically by email. IIAV members (in good standing for at least six months) can publish in IJAV free of charge and their papers will be displayed on-line immediately after they have been edited and laid-out. Non-IIAV members will be required to pay a mandatory Article Processing Charge (APC) of $200 USD if the manuscript is accepted for publication after review. The APC fee allows IIAV to make your research freely available to all readers using the Open Access model. In addition, Non-IIAV members who pay an extra voluntary publication fee (EVPF) of $500 USD will be granted expedited publication in the IJAV Journal and their papers can be displayed on the Internet after acceptance. If the $200 USD (APC) publication fee is not honored, papers will not be published. Authors who do not pay the voluntary fixed fee of $500 USD will have their papers published but there may be a considerable delay. The English text of the papers must be of high quality. If the text submitted is of low quality the manuscript will be more than likely rejected. For authors whose first language is not English, we recommend having their manuscripts reviewed and edited prior to submission by a native English speaker with scientific expertise. There are many commercial editing services which can provide this service at a cost to the authors.
