摘要：
The results of bending tests up to failure of pre-stressed slab beams, fitted and not fitted with concrete casting, pre-emptively subjected to high temperatures, provide a useful contribution to the study of the fire behavior of the structural elements regarded. Comparisons are made with similar beams not previously subjected to fire tests. The results obtained are interesting in evidencing the mechanical characteristics that can be more affected by fire in the two beam typologies tested. (C) 2013 Elsevier Ltd. All rights reserved.
