this report is presented as a guide to the design of prestressed concrete flat plates in buildings, post-tensioned with either bonded or unbonded tendons. The report presents: analysis and design procedures, permissable stresses for flexure and shear, reccomendations on tendon distribution and spacing, nonprestressed reinforcement requirements, span-depth ratios for deflection and camber control, seismic design provisions, fire resisting rating criteria, and construction reccomendations. The report is for the guidance and information of professional engineers who must add proper engineering judgement to applications of the reccommendations.
