Wind-induced motion on tall buildings: A comfort criteria overview

摘要

Comfort performance during wind-induced motions is an important building design issue. Several criteria concerning comfort evaluation are not agreed between different authors and different normative codes such as use of peak instead of root-mean-square (rms) acceleration; influence of waveform on comfort evaluation; and comfort evaluation based on users' perception and level of complaint. The discussion presented in this paper analyses comfort evaluation aligned with the hypothesis that, in the future, users must be aware of the building motions and educated to cope with it. Provided the building motion does not affect structural integrity and safety, an alternative approach for human comfort assessment to wind-induced motion might take place. Assessment of sustained vibration for nausea, task performance reduction and other compensatory behaviors might lead to less conservative structural design. (C) 2015 Elsevier Ltd. All rights reserved.
