随着建筑技术的进步和现代建筑楼层轻量化、大跨度结构布局的创新，抗振性日益成为主导设计标准。随着这一趋势的持续，人类活动引起的过度振动正成为一个重大问题。设计阶段的楼板振动预测通常使用当前可用的设计指南，如AISC设计指南11、混凝土学会技术报告43附录G、SCI P354、混凝土中心CCIP-016和HiVoSS。本文采用上述设计准则对典型办公楼层的振动响应进行了预测，并与实测响应进行了比较。很明显，不同的指导方针提供了不同的公差限制，这使得满意/不满意的决定不精确。结果表明，案例研究底板满足AISC-DG11、SCI P354和HiVoSS的要求，但CSTR43 App G和CCIP-016的要求不理想。然而，实验振动响应表明，有一个可感知的振动水平，但没有不利的评论。这些差异突出表明需要更好的预测技术和更可靠的评估标准。
Technological advances in the construction sector and innovative lightweight and large span structural layouts in modern building floors increasingly mean that vibration serviceability is the governing design criterion. As this trend continues, excessive vibrations induced by human activities are becoming a significant concern. Prediction of floor vibrations at the design stage is often done using currently available design guidelines, such as AISC Design Guide 11, Concrete Society Technical Report 43 Appendix G, SCI P354, Concrete Centre CCIP-016 and HiVoSS.In this paper, the aforementioned design guidelines are used to predict the vibration responses of a typical office floor, which are then compared with the actual measured responses. It is clear that different guidelines provide different tolerance limits which make the satisfactory/unsatisfactory decision imprecise. The results show that the case-study floor is unsatisfactory according to CSTR43 App G and CCIP-016, whereas it satisfies the requirements of AISC-DG11, SCI P354 and HiVoSS. Nevertheless, the experimental vibration response indicates that there is a perceptible level of vibrations but with no adverse comments. These discrepancies highlight the need for a better prediction techniques and more reliable assessment criteria.
