Floor Vibration Criteria: acceleration limit
residential#general#ISO 10137 to workshop#general#AISC DG11
Acceptable floor vibration levels by occupancy and floor system: acceleration limits (%g), minimum natural frequencies (Hz), damping ratios, and effective weight factors. Sources: AISC Design Guide 11 2nd Ed., SCI P354, ISO 10137:2007
