A review on numerical analysis of RC flat slabs exposed to fire

Abstract EN

This paper aims at presenting and discussing the numerical studies performed to estimate the mechanical and thermal behavior of RC flat slat elevated temperature and fire.

The numerical analysis is carried out using finite element programs by developing models to simulate the performance of the buildings subjected to fire.

Themechanical and thermal properties of the materials obtained from the experimental work are involved in the modeling that the outcomes will be more realistic.

Many parameters related to fire resistance of the flat slhave been studied and the finite element analysis results reveal that the width and thickness of the slab, the temperature gradient, the fire direction, the exposure duration and the thermal restraint are important factorsthat influence the vertical deflection, bending moment and force membrane of the flatslexposed to fire.

However, the validation of the models is verified by comparingtheir results to the available experimental date.

The finite element modeling contributesin saving cost and time consumed by experiments.
