Abstract
Construction of modular hospitals has gained significant attention since the global pandemic. One important design requirement for hospitals that is critical for their safe operation is to control floor vibration. Floors in modular buildings are often more prone to vibration because they are lightweight and less restrained. This study first presents a standardized design layout for modular hospitals developed based on Canadian code requirements. Then, the human-induced vibration of various floor systems designed for this sample modular hospital is investigated using different analysis methods including a new method developed by the authors. It is found that conventional floor designs may not be suitable for modular hospitals considering the strict vibration limits for hospitals and the need for lightweight construction. Using detailed FE analysis, it is shown that the proposed method can accurately predict the vibration response of various floors including those that have frequencies well beyond the application range of existing design methods.
自全球大流行病发生以来,模块化医院的建设受到了极大关注。医院安全运行的一个重要设计要求是控制地面振动。模块化建筑的地板通常更容易产生振动,因为它们重量轻、约束少。本研究首先介绍了根据加拿大规范要求开发的模块化医院标准化设计布局。然后,使用不同的分析方法,包括作者开发的一种新方法,对为该样本模块化医院设计的各种地板系统的人体诱发振动进行了研究。研究发现,考虑到医院严格的振动限制和轻质结构的需要,传统的地板设计可能并不适合模块化医院。详细的 FE 分析表明,所提出的方法可以准确预测各种地板的振动响应,包括那些频率远远超出现有设计方法应用范围的地板。
