Abstract(s)
The composite slab with steel decking is widely used in every type of buildings and requires fire
resistance, in accordance to regulations and standards. The concrete is usually reinforced with a
steel mesh on the top and may also be reinforced using individual rebars. The fire assessment
should consider the criterion for stability (R), Integrity (E) and insulation (I). The scope of this
investigation concerns the fire rating for the R and I criteria. Numerical simulations with finite
elements were developed, using ANSYS, to find out the thermal and mechanical effects of
standard fire exposure. The fire resistance criteria for loadbearing (R) depends on the maximum
displacement (D) or on the rate of displacement (dD/dt), while the fire resistance for insulation
depends on the maximum or average temperatures in the unexposed side. A literature review
from different investigations is presented [1] [2]. The results of the numerical simulation are
compared with experimental results to validate the model [3]. The results are also compared with
the simplified method proposed by Eurocode 4-part 1.2 [4].
