Abstract

Recent seismic events have highlighted the vulnerability of reinforced concrete buildings, especially soft-story structures, to damage and collapse during strong earthquakes due to the ground's vibrational response. This study aims to mitigate these adverse vibrations using passive control mechanisms, particularly tuned mass dampers (TMDs). Conventional TMDs require a substantial mass to effectively influence the structure's lateral reactions. The research explores the use of multi-tuned mass dampers (MTMDs) and double-tuned mass dampers (DTMDs) in a soft-story building. The study uses MATLAB to estimate TMD parameters and subject the models to seismic loading. The comparative assessment of these models reveals the potential benefits of using MTMD and DTMD systems to enhance the seismic resilience of soft-story structures.

软层结构中多重调谐质量阻尼器与双调谐质量阻尼器的比较研究

最近的地震事件凸显了钢筋混凝土建筑的脆弱性，特别是软层结构，由于地面的振动反应，在强震期间容易损坏和倒塌。本研究旨在利用被动控制机制，特别是调谐质量阻尼器(TMDs)来减轻这些不利的振动。传统的tmd需要相当大的质量来有效地影响结构的侧向反应。研究了多调谐质量阻尼器(MTMDs)和双调谐质量阻尼器(DTMDs)在软层建筑中的应用。利用MATLAB对TMD参数进行估计，并对模型进行地震荷载作用。通过对两种模型的对比分析，揭示了MTMD和DTMD系统在提高软层结构抗震性能方面的潜在优势。

期刊介绍： World Earthquake Engineering was founded in 1985 and is now a quarterly journal. It is an academic journal in the field of earthquake engineering under the supervision of China Earthquake Administration (CEA), and co-sponsored by the Institute of Engineering Mechanics of China Earthquake Administration (IEMCA) and the Chinese Society of Mechanics (CSM). The journal aims to introduce the latest research results in the field of earthquake engineering at home and abroad, to promote international academic exchanges in the field of earthquake engineering, and to serve China's seismic prevention and anti-seismic work. China Association for Science and Technology (CAST) selected China's high-quality scientific and technological journals in different fields for its hierarchical catalogue, and the journal was selected as T2 level (internationally renowned journals) of earth science and geophysical journals. Outstanding journal for the implementation of the CAJ-CD Code in the implementation of the Chinese Academic Journals (CD-ROM Version) Retrieval and Evaluation Data Specification (CAJ-CD Code) in the evaluation of excellence activities; included in the cultivation bank of Heilongjiang Province's high-quality journal projects.
