The Statnamic load test is a type of test for assessing the load-carrying capacity of deep foundations which is faster and less expensive than the static load test. The Statnamic test was conceived in 1985, with the first prototype tests carried out in 1988 through collaboration between Berminghammer Foundation Equipment of Canada and TNO Building Research of the Netherlands. Guidance on rapid load pile testing can be found in: Methods for Axial Compressive Force Pulse (Rapid) Testing of Deep Foundations. Sanken D7383 - 08 Standard Test. How it works Statnamic testing works by accelerating a mass upward that in turn imparts a load onto the foundation pile below the Statnamic device. The load is applied and removed smoothly resulting in load application of 100 to 200 milliseconds. This is 30 to 40 times the duration of dynamic pile load testing. As the duration of the loading is relatively long, piles less than 40 m in length remain in compression throughout, resulting in negligible stress wave effects and potentially simpler analysis. For foundation design it is necessary to derive the equivalent static load-settlement curve from the Statnamic data. The simplest form of Statnamic analysis used to obtain equivalent static pile response is known as the unloading point method (UPM). The UPM analysis method was conceived to be simple and based on measured results alone. The Statnamic test applies a force to the pile head over a typical duration of 120 milliseconds by the controlled venting of high-pressure gas. The gas is the product of the combustion of a fast-burning fuel within a piston (fuel chamber) (Figure 1). At the top of the piston are vent holes that are sealed by the load hanger retaining the reaction mass. At some point the pressure within the piston is of such a magnitude to force the load hanger arrangement upward at accelerations in order of 196m/s2 (20g). This process applies a load downwards on the test pile. During the loading sequence the load applied to the test pile is monitored by a calibrated load cell incorporated in the base of the combustion piston. Pile settlement is measured using a remote laser reference source that falls on a photovoltaic cell incorporated in the piston. The laser reference source should be placed at least 15 m from the test pile to avoid the influence of test-induced ground surface wave disturbance (Brown & Hyde, 2006). Data capture
