Long-time loading-tests of concrete waffle slabs with cast-in-place and prestressed joist ribs were conducted for investigation on the control of their flexuial cracking at the time of construction and their long-time deflection. The deflection was restrained by strains caused by prestressing, which stopped its progress within two years or so. The prestressing force used for both cracking and deflection control was 12 kef/cm^2 in intensity. Practical approximation is obtained between experimental and calculated long-time deflection of an uncracked two-way slab by a proposed practical formula. Using slab systems of the currently introduced type can provide systematic methods for constructing building structures.
