Some tips: Typical walking speed is 1.25 to 1.5 Hz, or steps per second. Floor frequencies should be kept well above the range of 2.5 to 3 Hz, the second harmonic for walking frequencies. When evaluating a floor for vibration perceptibility, the designer should assume lower floor loadings than are required in designing for structural strength.

When planning for a new building framed with structural steel, here are a few tips. Beam Depths. For determining beam depths, a reasonable estimate is that the depth of the beams will be equal to the span divided by 24 (L/24). Another way to state it is ½" of depth is required for every additional foot of span. Most structural steel systems ...

According to the UK National Annex to BS EN 1990, 30% of the imposed load should be included when considering deformation at serviceability limit state. However, this is likely to be inappropriate for floor vibrations because, in reality, the actual imposed load will be considerably less than the prescribed design loads on the floor.
