Shallow floor construction with deep composite deck: From fire tests to simple calculation rules

Abstract

This paper deals with an international research project into the fire behaviour of a particular, economically appealing, type of composite steel concrete beams: the shallow floor beams with composite slabs using deep deckings. The results of 3 full scale fire tests are briefly summarised. Based on these fire tests, advanced numerical models have been established enabling accurate simulation of the fire tests as well as a parametric study into relevant factors affecting the overall fire behaviour of this type of composite structures. The outcome of the parametric study is transformed into economic, yet easy to handle calculation rules for engineering practice.
