Sway comfort level
Sway comfort level
(OP)
Anyone know of a survey of "comfortable" or "discernible" building sway due to wind loading (not seismic drift limitations)? I assume this will be noted as a max lateral deflection as a percentage of the building height (ie. H/1000) or preferably, for this application, by an acceleration limit (ie. 0.05g). Thanks-

Do not forge that vibrations also come to play. Dr. Tom Murray at Virginia Tech wrote AISC design Guide number 11 which deals with the vibrations and human comfort thresholds. Dr Murray also wrote software that deals with the study of vibrations. SJI also published a booklet and software that deals with the same subject.
It is my opinion that it is all relative to the person. The general guide lines to limit lateral drift for structures seem to work well since most of the existing buildings are designed to these limitations.
