在人的内部激励下，楼板结构的振动适用性是决定新建结构和已改建或改变用途的结构是否可接受的关键标准。为了帮助结构工程师设计这种地板和评估振动环境，有许多指导方针和标准提出了各种占用的限制。本文主要研究了办公楼板在人为激励下的振动适用性，并对四个典型办公楼板结构的全天监测结果进行了分析。评估了各种指导性文件中提出的限值的可靠性，主要结论是基于R因子的限值不是特别可靠，而基于振动剂量值的评估更可靠，但目前BS6472中规定的限值可能过高。
Vibration serviceability of floor structures under internal human excitations is a key criterion that determines the acceptability or otherwise of both new-build structures and those that have been altered or subjected to a change of use. To assist structural engineers in the design of such floors and the assessment of the vibration environment, there are a number of guidelines and standards that propose limits for various occupancies. This paper focuses on vibration serviceability of office floors under human excitation and examines actual responses acquired from whole day monitoring of four typical office floor structures. The reliability of the limits proposed in the various guidance documents is assessed, with the key conclusions that limits based on R factors are not particularly reliable and assessments on the basis of vibration dose values are more reliable but the currently specified limit in BS6472 may be too high.
