A novel strain-based finite-element numerical model for the fire analysis of curved reinforced concrete (RC) beams is presented. In addition, the effect of load level and boundary conditions on fire resistance of the curved RC beam is observed.

COBISS.SI-ID: 6237281The 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 vapour-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.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 6355041This research work discusses the fire safety design for residential buildings in a comprehensive manner. Prescriptive rules and performance-based approach to fire safety design and the application of an advanced computer program for modelling a fire development in an enclosure are presented. A fire safety scheme of terraced houses is presented in graphical and textual forms according to the Slovenian codes. The focus of the present work is on numerical modelling of a fire spread in the ground floor of a terraced house, using the computer program Fire Dynamics Simulator. The effects of the mesh density, the area of origin of the fire, the temperature of ignition of an obstruction and the ventilation on fire dynamics are considered. The performance-based approach to design fire safety of structural elements is presented in the context of the fire analysis of a steel beam. The time evolution of air temperature around the beam is estimated with the use of the computer program Fire Dynamics Simulator for the worst case fire scenario. Simplified calculation methods given by the standard SIST EN 1993-1-2 are used to prove the fire resistance of a steel beam.
