STUDY ON FIRE RESISTANCE OF REINFORCED CONCRETE SLAB UNDER THE POSITIVE BENDING MOMENT

Abstract

This paper describes experimental and analytical studies on the fire resistance of a reinforced concrete slab under the positive bending moment. As the result of fire resistance tests, it became clear that a top reinforcement influences greatly the fire resistance of a reinforced concrete slab. The analysis results was well in agreement with the experimental results. Simple appraisal method for the fire resistance of a reinforced concrete slab which allowed the influence of a top reinforcement was proposed. It checked that this appraisal method is able to evaluate the fire resistance of a reinforced concrete slab appropriately.
