The calculation analysis of the prestress concrete beam, and the design of the reirforcement and the unbonded prestress basement roof are presented, which affords succestful experience for floor design of domestic similar scale building.
Keywords: adhesive (unbonded) prestress; long-span cantilever; super plane; expansion joints
