Implementation of Shallow Foundations on Florida Limestone in FB-MultiPier

The project objectives are to implement new shallow foundation analysis features and user interface (UI) controls into the existing bridge FEA software package, and to develop corresponding software documentation. The objectives correspond to thrusts in the following areas: (1) implementation of bearing capacity equations for Florida limestone to facilitate predictions of shallow foundation capacities in design applications; (2) implementation of nonlinear load-settlement analysis for bearing on Florida limestone so that distributions of internal forces throughout bridge substructures and pressures that develop in the underlying limestone can be predicted; (3) development and implementation of lateral resistance of shallow foundations, which is required for stability of the numerical model; (4) investigation of the effects of inclined and eccentric loads applied to shallow foundations; and (5) documentation of outcomes and feature sets from the above four thrusts within the FEA software manual.
