FEAFAA (Finite Element Analysis - FAA) was developed by the FAA Airport Technology R&D Branch as a stand-alone tool for 3D finite element analysis of multiple-slab rigid airport pavements and overlays. It is useful for computing accurate responses (stresses, strains and deflections) of rigid pavement structures to individual aircraft landing gear loads. FEAFAA is not intended for use as an FAA design procedure. For performing pavement thickness designs in conformance with FAA standards, please download FAARFIELD.

FEAFAA makes use of the 3D finite element program FAASR3D (FAA Structural Response – 3D). FAASR3D is based on the NIKE3D program, originally developed by the U.S. Dept. of Energy Lawrence Livermore National Laboratory (LLNL).

Note: Minimum requirements to run FEAFAA 3.0 are Windows 7 or higher with 4.0 GB of RAM. FEAFAA 3.0 is compiled to run on 32-bit or 64-bit operating systems.
