PROBLEM TO BE SOLVED: To provide a demolition method of middle-high-rise building capable of solving problems of surrounding environments, safety and cost by performing the work in a simple and easy manner.SOLUTION: The demolition method repeats a cut and lowering work of floor slabs and beams in order from the uppermost floor to the lower floor of a middle-high-rise building B to be destruction, including the steps of: receiving floor slabs 1 and beams 2 of the upper floor by using plural hydraulic jacks J which are interposed between the upper floor and the lower floor; cutting off every posts 3 on the lower floor; and lowering down the floor slabs 1 and beams 2 of the upper floor on the floor slab 1 of the lower floor by contracting the hydraulic jacks J. Thus, the floor slabs 1 and beams 2 of the upper floor are lowered being piled up on the floor slab 1 of the lower floor in order.
