Numerical Modeling of Composite Floor Slabs in Fires
Full-scale fire tests have shown that composite floor slabs behave well in fires even with unprotected steel beams. The main reason for this favorable behavior is the membrane forces caused by large deflections in the reinforced concrete slabs. A tailor-made finite element program called SlabFem which takes membrane forces into account is being developed to investigate this problem. The main focus of this paper is on a new approach to model the flexible shear connection between the steel girder and the reinforced concrete slab. When the temperature increases the steel beams loose their strength if they are not protected and the shear studs get more flexible. This has a direct influence on the load carrying mechanism.
