What's FAD TOOLS?

Fad Tools is a collection of three foundation design modules used to design and analyze foundations for transmission line structures. Each module is based on a semi-empirical models developed from full-scale foundation tests and calibrated for Reliability Based Design (RBD).

MFAD designs drilled shaft and direct embedded pole foundations subject to high overturning loads, moment and axial loads.

HFAD designs drilled shaft and direct embedded pole foundations for H-frame pole structures subject to a combination of overturning loads, horizontal shear and uplift or compression loads.

TFAD designs drilled shaft foundations for tower structure legs subjected to a combination of horizontal shear under uplift or compression loads.

Why use FAD TOOLS?

Semi-empirical model based on full scale load tests.

Geotechnical resistance models for both soil and/or rock.

Designs foundations for combined, moment, horizontal shear, and compression loads.

Designs foundations for combined, moment, horizontal shear, and uplift loads.

Considers the engineering properties of backfill for direct embedded poles.

Calibrated for Reliability Based Design (RBD).

Designs short-rigid shaft foundations, which are typical for the transmission line industry.

FAD is based on a four-spring model including lateral, side shear, base moment, and base shear springs.

Users can select springs and modules to best reflect particular design conditions.

Load-deflection graphs and tables are provided to evaluate various load and performance scenarios (free head push over analysis).
