IMPORTANT! Failure analysis modes evaluated follow ACI 318-14,
chapter 17. This DOES NOT include evaluating the base material (e.g.
edge-of-slab) capacity to resist compressive forces generated by
the fixture. The engineer must ALWAYS verify the base material (e.g.
edge-of-slab) design is capable of resisting the applied loading.
