Predetermining the ultimate capacity of piles driven into purely
cohesive soils and purely cohesionless soils involves, respectively,
the consideration of soil shear strength in a completely undrained and
a completely drained condition. For the intermediate cases concerning
soils that possess both cohesion and internal friction (silts, clayey
silts, sandy clays,...
This paper presents a method of predicting penetration
resistance for driven piles, using known driving records for driving
the same type piling in similar subsurface conditions. As known
driving records are not always available to the analyst, a method was
also investigated using soil data only. The analytical tools employed...
Pile caps are structural elements used to transmit loads from structural columns into pile groups. A pile cap is generally constructed of reinforced concrete and contains only minimal flexural reinforcing steel. Using modern design methods, the anchorage of the flexural steel may limit the design capacity of existing pile caps....
The structural behavior of pile groups (dolphins) is analyzed
considering two types of boundary conditions. First the individual
piles of the group are assumed to be rigidly embedded in the soil. In
the second analysis the more realistic case is considered where the
soil foundation is allowed to yield. The...
This study uses an existing database of dynamic loading tests of driven piles installed in the Puget Sound Lowlands to improve the reliability of axial performance. First, the unit shaft resistances developed from stress wave signal matching to dynamic records of pile installation are used to develop an effective stress-based...
Deep foundations, including driven piles, are used to support vertical loads of structures and applied lateral forces. Many pile supported structures, including bridges, are subjected to large lateral loads in the form of wind, wave, seismic, and traffic impact loads. In many practical situations, structures subjected to lateral loading are...
Pile supported bridges are typically constructed near or in a natural or man-made
slope and are subjected to lateral loading. The current design method for laterally loaded
piles involves the use of Winkler's spring concept with the standard nonlinear p-y curves.
The available p-y curves were developed based on results...
