Reaction wall, reaction floor
- Dimension of reaction floor:
11m (width) ×15m (length) ×1.4m (thickness) - Dimension of reaction wall:
11m (width) ×8.5m (length) ×1.5m (thickness: partially 2.5m) - Strength of reaction wall:
Bending strength 2000 ton･m (entire wall)
This large experimental equipment is aimed at evaluating structural strength, rigidity, and toughness by installing a whole building frame or test piece of partially combined member, and applying force by a hydraulic jack. Normally in the experiment, an actual building frame is built on the reaction floor and pressed by a hydraulic jack from the reaction wall. For that purpose, rigid floor and wall are essential. Both the wall and floor are made of thick reinforced concrete and supported by high-strength reinforcing steels called PC reinforced rods.
