Influence of moisture on fire resistance of side-plated RC beams

Abstract

The objective of the paper is to present the effect of moisture in concrete on the fire resistance of side-plated reinforced concrete (RC) beams. For this purpose an adequate new finite-element (FE) procedure is presented. The paper concludes with a parametric study, examining the impacts of the vapor-tight side plates, high initial moisture content and low initial permeability of concrete of the selected RC beam on the rate of the risk of concrete spalling.
