Fire Behavior of Two-Way Post-Tensioned Concrete Slabs Provided with Bonded Tendons: An Experimental Study

Abstract

Fire tests of three reduced-scale two-way post-tensioned concrete slabs with bonded tendons were carried out. This study was intended to investigate the influence of the layout of prestressing tendons, prestressing force and concrete spalling on the structural response of two-way post-tensioned concrete slabs with bonded tendons in fire. The material used to fabricate the specimens, the phenomena observed during the tests, the temperature distributions, the deflections and occurrence of concrete spalling were investigated.
