人致结构振动舒适度评估标准研究综述

Review on evaluation criteria of human⁃induced structural vibration comfort

人致结构振动在大跨工程结构设计中日益受到重视,但振动评价标准的相关研究却相对滞后。首先通过文献的知识图谱分析,得到了近期研究关键词的共性分析图、聚类分析图和突现性表。结果表明:振动舒适度限值是振动舒适度领域近期研究的热点。进而从试验研究和标准规范两个维度,对近百年来代表性的振动舒适度限值研究进行了梳理,整理了近40部规范的规定及相互承启关系。结果表明:传统研究方式难以避免人的特殊性和主观感受差异性对试验结果的影响,各规范存在数据基础薄弱、振动指标不统一、影响因素单一、覆盖性和延续性差等问题。最后讨论了未来两个可能的工作方向。

Human⁃induced structural vibration is increasingly important in the design of large⁃span engineering structures,but research on vibration evaluation standards has lagged behind.Firstly,through knowledge graph analysis of the literature,commonality analysis charts clustering analysis charts and burst tables of recent research keywords were obtained.The results show that vibration comfort limits are a hot topic in the field of vibration comfort.Then,representative studies on vibration comfort limits over the past century from the perspectives of experimental research and standards were reviewed.The provisions and mutual inheritance relations of nearly 40 specifications were sorted out.The results show that the traditional research method is difficult to avoid the influence of human particularity and subjective feeling difference on the test results.There are some problems in each specification,such as weak data base,inconsistent vibration index,single influencing factor,poor coverage and continuity.Finally,two possible directions for future work were discussed.
