Table below summarizes the shear wave velocities (Vs30) along with site classification based on different codes.
Table: Shear Wave Velocities (Vs30) in various US Codes
Where:
•Vs30: Shear Wave Velocity
•N: Field Standard Penetration Resistance
•Nch: Standard Penetration Resistance for Cohesionless Soil Layers
•Su: Undrained Shear Strength
