Temperature field of composite steel and concrete slabs in fire situation

Abstract Composite steel decking concrete slabs are an important structural member in building construction. Research on its thermal behavior should be developed to understand fire performance. In this paper, a comparison of the temperature distribution cross-section subjected is made through three different procedures: (a) standardized analytical, (b) experimental and (c) numerical. The analytical method was one proposed NBR 14323 standard. tests corresponding eight real-scale composite carried out by authors. numerical were done for same configurations used FEA software Abaqus. Steel temperatures obtained with methodologies showed good convergence ones. not observed concrete, positive negative rebar.
