Rapid Load Testing Damping Analysis


Introduction

The damping associated with dynamic or statnamic tests has typically been over simplified to provide a “catch-all” factor for those responses that could not be fully accounted for using present analyses. This factor has historically been considered constant for a given pile - soil system, but recent investigations show the plausibility of another explanation. USF researchers are currently conducting a study which hopes to entertain the hypothesis that damping is more closely associated with the increase in strain and not the total strain. Therein, the change in the volumetric strain is being scrutinized to investigate its relationship to damping. To validate this assumption, numerical and physical models of drilled shaft foundations are being created and the load test results analyzed to determine the change in the extent of the zone of influence surrounding a pile and volumetric contribution of soil to damping.
