| Abstract: | During the pre-stressing of the unbonded prestressed concrete wide flat beam-waffle slab system, the displacements and strains of slab and the prestressed concrete beams were site-measured and the results were analyzed.The prestressing construction was simulated by finite element program.The prestressing efficiency of the unbonded prestressed concrete wide flat beam-waffle slab system was discussed.It indicates that the prestressing efficiency was affected by the in-plane stiffness of slab. |

| Keywords: | prestressed concrete flat beam waffle slab site-measurement prestressing effect |
