Unformatted text preview: (a linear function of the penetration velocity and a damping constant) o soil model is crude but effective o modern computers have improved our computational capability (thank you 18M) o first program from Texas (TIl), followed by FHWA research (WEAP), now marketed by Pile Dynamics, Inc. as GRLWEAP o possible to do rational parametric studies for different pile and hammer configurations o especially useful for drivability studies and pile stress predictions o still needs refinement in areas of dynamic stiffness (1.1 to 1.5 times static stiffness) and correlation of standard soil properties to spring-dashpot model...
