For this type of testing on reinforced concrete structure, special fibreglass containers have been used which we realized, of dimensions 0, 30×1, 00×1, 00, for the ramps and swimming pools m. 2×2 for the landings. The load was then reached by filling the tanks with water following precise loading steps, then evaluating the sagging obtained by measuring points, made with telescopic rods and centesimal comparators, placed in contrast under the structure.
