Steel 147 173 APPENDIX T Velocity Limits for Buildings Recommended limit values for traffic are given in Table T-1, as taken from References 22 through 24. The peak value is taken from the velocity time history. Table T-1. Recommended Ground Limit Values for Traffic Recommended Vertical Velocity Type of building and foundation Vmax (mm/sec) (in/sec) Especially sensitive buildings and 1 0.039 buildings of cultural and historic value Newly-built buildings and/or foundations 2 0.079 of a foot plate (spread footings) Buildings on cohesion piles 3 0.12 Buildings on bearing piles or friction piles 5 0.20 The vertical velocity is with respect to the ground vibration. The specification implies that building stress correlates more closely with velocity than with either displacement or acceleration.
