The chamber is supported by springs on its perimeter. The design live load for the floor is equal to 250 kgf/m2. The design live load for the ceiling is equal to 50 kgf/m2.
Specific weight (concrete) = 2320.0 kgf/m3
Surface (ceiling) = 10.9 m2
Volume (wall, ceiling) = 4.8 m3
Wall perimeter = 12.82 m

The weight of the wall, the weight and the live load of the ceiling were applied as force on the edges of the floor. The force/length on the edge can be calculated as (4.8 * 2320.0 + 10.9 * 50) / 12.82 = 911 kgf/m.
