Does anyone know of any references for designing something like a concrete reaction floor and 'strong wall' for a structures lab? I realize this is probably too niche to have its own guidelines, but perhaps there are references for structures with similar design criteria. The basic scheme is a thick slab and wall with a grid of sleeves for anchoring actuators, specimens, and testing apparatus. The slab will likely be supported on a grid of closely spaced walls, then a foundation slab, to provide access to the underside of the floor. The wall cantilevers up from the slab. It may be L-shaped and/or pilastered to help with out of plane bending. Some labs I've visited have PT'd their walls, but that was seemingly because the wall was a later addition.

Some of the unique aspects include:
- Stiffness criteria much more important than conventional structures.
- Will see large cyclic loads over its life, and need to remain uncracked.
- High uncertainty / variability in loads
