The strong wall on the east side of the Laboratory is intended for small-scale experiments. It is a vertical cantilever projecting from the exterior wall of the basement.

Reinforced with mild steel, the wall has been post-tensioned to a uniform compression of 950 psi (6.5 MPa).

Load rating is limited by the allowable tensile and compressive stresses in the pre-compressed zone at the base of the wall.

The wall is 20 ft wide, 19 ft high and 2 feet thick (6.1 x 5.8 x 0.61 m). It is perforated with tie-down holes on the same 2 ft by 2 ft (0.61 x 0.61 m) grid as the test floor.

The wall may be used in conjunction with modular reaction blocks to permit a variety of reaction and anchorage loading configurations including L-shaped systems.
