Recent developments and integration of design codes for steel-concrete composite structures in fire

Abstract

[EN] This paper presents a review on the latest advances in the field of steel-concrete composite structures exposed to fire, studying the recent research in the area and developments of the design codes. The paper focuses in particular on concrete-filled steel tubular columns and slim-floor beams, topics where the authors have carried out extensive research during the last years. The more recent experimental and numerical studies are presented, as well as the currently available design methods for the calculation of isolated members in the fire situation. The use of advanced materials, such as high strength steel and concrete, stainless steel, lightweight concrete or geopolymer concrete is considered for the enhancement of the fire behaviour of concrete-filled steel tubular columns and slim-floor beams.
