ABSTRACT:
Concrete structures including horizontal structures such as slabs, sub-beams and main beams and vertical structures such as internal walls, external walls and columns are broken by a static load applied to the concrete structure by a loading member of a static loading means, which causes bending stress to build up in the concrete structure and finally brings about breakage of the structure. The static load may be applied by hydraulic means, preferably mounted on a movable vehicle.
