Summary

Post-tensioned concrete flat slabs are considered a competitive structural form of construction to traditional reinforced concrete. Traditionally the post-tensioning tendons are placed in draped profiles that have various layouts to provide the load balancing capacity. At the extreme these are banded/banded and distributed/distributed layouts in which the post-tensioning tendons are concentrated in the column strips or uniformly distributed along the field and column strips, respectively. This would force the slab to behave primarily in a one-way or a twoway fashion. This paper presents the evaluation of the nonlinear behavior of posttensioned flat slabs with various tendons profiles and different modules aspect ratios. The main focus is to systematically evaluate the effect of different tendons arrangements on the various panels' maximum deflection, service and ultimate loads and prestressing camber. Key results showed a difference in the service and ultimate load carrying capacities of the floors with different layouts and with the same prestressing amounts. Significant differences in the ultimate deflections for various panels were also observed.
