The object of this study is the deflection control of the prestressed concrete slab in post-tensioned by the parameter study through the computer simulation.
The relationship between prestressing effect and external load, deflection of slab are inspected. Through the controlling factor that is effect on the deflection, in order to minimize prestressed concrete slab deflection largely effected dominant factor on deflection is found. Loading condition is limited in the service load and the effect of crack is not included by the full prestressing.
The analysis method is the F.E.M. and the load balancing method by T.Y. Lin. In order to generalize the results, the ratio of them is figured in Appendix.
