Preliminary Study of the Tendon Arrangement in Prestressed Concrete Flat Slab

The behaviours of prestressed concrete flat slabs with tendons uniformly distributed in both directions or uniformly distributed in one direction and concentrated within slab strips over columns in the other direction or concentrated within slab strips over columns in both directions are calculated by using finite element method and load balancing method. On the basis of the calulated results and the existing test data, the advantages and disadvantages of the above tendon arrangements are discussed. It is suggested that the form with concentrating tendons within slab strips over columns is the best one.
