抄録

The degree of human perception of vibration of floor slabs generally is estimated in terms of major vibration criteria, natural vibration period Ti and amplitude 8. As for f we have already proposed regression equations for it as a function of long-time floor deflection, which were derived from systematic analyses of our so far accumulated field data; thus enabling direct and simple estimation of Ti using long-time floor slab deflection obtainable by any standard method. Currently, resulting from further analysis using the same data, a strong functional relation has proved to exist between those Ti and 6 caused by walkers. Accordingly, our last and present formulation combined may enable us to quantify human perception of floor vibration approximately by available vibration evaluation curves such as Meister1 s which use both of the said criteria.
