Behaviour up to failure of statically determined and indetermined slabs with prestressed joists

Abstract

In this article, the experimental results of one-way slabs with prestressed joists, submited to load up to failure at the age of 28 days, are presented. Special attention is given to the results of statically indetermined slabs. They show a very marked nonlinear behaviour, both for service loads and ultimate loads. The influence of the reinforcement disposal is also pointed out.
