'''Dynamic load testing''' (or '''dynamic loading''') is a method to assess a [[Deep_foundation|pile]]'s [[bearing capacity]] by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. Dynamic load testing is a ''[[high strain dynamic testing|high strain dynamic test]]'' which is applied ''after ''pile installation.
The procedure is standardized by ASTM D4945-00 Standard Test Method for [[High Strain Dynamic Testing]] of Piles. It may be performed all piles, regardless of their installation method. In addition to bearing capacity, Dynamic Load Testing gives information on resistance distribution (shaft resistance and end bearing) and evaluates the shape and integrity of the foundation element.
