Unformatted text preview: categories: momentum conservation, combined wave mechanics with energy conservation, and wave mechanics alone. The methods are the Engineering News Record (ENR), Modified ENR, FDOT, Gates, Paikowsky, Sakai (Japanese), Pile Driving Analyzer (PDA) and the Case Pile Wave Analysis Program (CAPWAP). In the following sections, a brief description of each method is presented. Momentum Conservation ENR One of the older formulas developed to estimate the driven pile capacity was the formula published in the Engineering News Record (ENR) (Coduto after Wellington, 1994). It has since become known as the Engineering News Record formula:...
