Sažetak:
The paper presents an experimental study of behaviour of a prestressed hollow-core slab exposed to ISO fire curve. Dimensions of the slab are 1, 2 × 8, 0 m. The study includes measurements of temperature gradient inside the section of the slab, voids, and upper surface of the slab. Time dependent vertical deflection of the structure was recorded by using two linear variable differential transformers (LVDT). Two additional LVDTs were used for tracking the rotation at the end of the slab. In addition, measurements of the time dependent longitudinal deformation of the slab at midspan were also carried out with two strain gauges. The study has shown that the behaviour of slab under fire depends on the temperature of the prestressed strands, combined with the degradation of the modulus of elasticity of the heated concrete. Shear failure had no effect on the load bearing capacity of the slab.
