Steel Floor Walking Vibration (AISC DG11)
AISC Design Guide 11 walking-vibration check: peak acceleration ap/g = P0 e^(-0.35 fn) / (beta W) against the occupancy limit (0.5% office/residence, 1.5% mall). Stiffer is not automatically better -- low-frequency floors (4-8 Hz) resonate with the walking harmonic. The serviceability check strength alone misses.
Formula and source
ap/g = P0 x e^(-0.35 x fn) / (beta x W); pass when ap/g <= ao/g.
AISC Design Guide 11 (2nd ed.) walking-vibration serviceability check, by name.
