A new construction method, in which a structure is built by lifting concrete waffle slabs along built-in columns, is being proposed. In order to realize such a procedure, the stress transfer mechanism at the slab-to-column joint has been experimentally investigated. The results indicate: (1) that the ultimate strength of the slab-to-column joint is represented by the strength when slipping occurs at the slab capital at which the slab is attached to the column by cast-in-placed concrete; (2) that the ultimate transfer of moment at the joint, when only lateral load is applied, is equivalent to the sum of the ultimate flexuial moments and torsional moments that acts on the side of the column, and the added moment by shear friction on the joint resulting from the dowel action at the flexural reinforcement; and (3) that the ultimate transferring moment, calculated based on this stress transfer mechanism, agrees favorably with the experimental result.
