The purpose of this manual is to document the calibration of FAD Tools 5.1 and to present the methodology used to assign geotechnical design parameters for the calibration process.
The user is assumed to recognize that the assumed geotechnical parameters used in design will have a significant effect on foundation performance and reliability. Ultimately, the user is responsible for selection of geotechnical design parameters, understanding the impact of the selected parameters on the reliability of the foundation design, and all acceptance, interpretation, and use of the FAD Tools program output.
Also, the user is responsible for understanding the basis and assumptions associated with the model being used for foundation design. For example, the model presented in Chapter 3 for MFAD 5.1 was calibrated based on the selection of “average” parameters from the correlations presented herein. Through that calibration process, a strength reduction factor of 0.63 was built into the program to calculate a 5% lower exclusion limit capacity. Therefore, if using FAD 5.1, the user is encouraged to maintain usage of “average” parameters unless special circumstances warrant a deviation(s) from this approach.
