抄録

Analyses of on-site collected pedestrian vibration data on examples of reinforced concrete floor slab systems are conducted and result in findings as follows mainly concerning the damping ratio for floor vibrations which is an essential measure or index of the degree of pedestrian perception but has been left virtually not quantified. (1) A strong relationship proves to exist between the damping ratio and the long-time deflection multiplier, basically a measure of normal or partly impaired structural serviceability of floor slab systems. (2) An approximate equation is derived for the above relation. (3) The effect of live loads on the above index is accounted for.
