Different Types of Pre-Stressed Hollow Core Panels and Their Fire Resistance According to Eurocodes

Abstract

The authors' work deals with the calculation of the fire resistance of pre-stressed hollow panels. The thermal characteristics of air in the hollows were determined on the basis of testing the fire resistance of two Spiroll panels, thickness 250 mm, with hollows with circle section. The thermal characteristics of the air in the hollows were used to compare the fire resistance of similar pre-stressed panels with different hollows, thickness 200 mm; Echo with hollows with oval section and Elematic with hollows with circle section. Furthermore the fire resistance is analysed in term of the concrete cover; a smaller concrete cover responds to a higher load-bearing capacity for a permanent design situation but decreases the final fire resistance. The calculated fire resistance is compared with the fire resistance determined by testing, if the results are available.
