Because of their economy, dynamic loading tests can be done on numerous piles at a site, whereas static loading tests must be limited to one or only a few piles. Modern codes such as American Association of State Highway and Transportation Officials specifications allow for increased resistance ...

The overall aim of the study was to compare dynamic and static test data, for open- and closed-ended piles driven into dense sand, for a range of delivered hammer energies. Open- and close-ended model piles were driven into dense sand and statically load tested at different penetrations, ...
According to the experience of Great Hanshin Earthquake, the seismic safety factors were considered for the structural design. To save the construction cost, it was planned to install large diameter steel pipe piles into the thin gravelly sand stratum. Series of Statnamic and Dynamic load tests ...
The equipment was first introduced into Australia by the then Country Roads Board of Victoria (now Vicroads) in 1982, as a means of economically testing a number of large diameter bored piles socketed into rock. The work proved to be a spectacular success (Balfe 1984), with predictions of ...
Load Testing and Interpretation of Instrumented Augered Cast-in-Place Piles Given that piles are composed of different materials and installed using a variety of methods, ASTM D 1143/D 1143M-07 Standard Test Methods for Deep Foundations Under Static Axial Compression is justifiably general so that...
