Drivability of Vulcan Hammers and Other Pile Driving Equipment

This section of vulcanhammer.info is about the drivability and performance of pile driving equipment in general and Vulcan hammers in particular. It’s divided into several sections: Dynamic formulae: the original method of relating hammer performance to pile capacity and resistance Before Wellington and ENR: Early Dynamic Formulae, and Sanders’ Formula The Engineering News Formula, and Its Treatment … Continue reading Drivability of Vulcan Hammers and Other Pile Driving Equipment

Pile Soil Interaction (including Static Capacity Analysis of Piles)

The Action of Soft Clay Along Friction Piles: Bay Mud Revisited Lymon C. Reese 1983 Research at Berkeley more than three decades ago gave new insight into the behaviour of axially-loaded piles in clay. Numerous experiments and analytical studies performed since, many of which have been supported by the oil industry with respect to offshore … Continue reading Pile Soil Interaction (including Static Capacity Analysis of Piles)

Pile Capacity Programs and Spreadsheet: Axial and Lateral

The ultimate objective of any driven pile is to carry some kind of load. These loads come from a variety of sources, as seen on the right. Once the loads are established, the pile’s resistance to the loads must be established. The interaction of piles and the surrounding soils–axial and lateral–is complex. Computer software and … Continue reading Pile Capacity Programs and Spreadsheet: Axial and Lateral
