Steel Buildings in Europe

Part 6: Fire Engineering 6 - 36 flanges are filled, to ensure that the top flange of the steel beam remains relatively cool in fire. Composite beams may be simply supported or continuous. Their design sagging and hogging moment resistances as well as their vertical and longitudinal shear resistances can be determined by using the simple models given in §4.3.1, §4.3.4 and Annex E of EN 1994-1-2. Resistance of composite columns The simple model for buckling resistance of composite columns is based on the assumption that the building is braced and the column has no horizontal displacement. The calculation rules are given in §4.3.5 and Annexes G and H of EN 1994-1-2.
