Title of the articleThe load capacity of composite steel roof system
Abstract.In article the composite steel roof system are reviewing wich including certain steel deck, girder and roof deck. The example of damaging such roof system has reviewed and causes of this damaging were established. Through conducted research the finite element model was created by Ansys software this model included girder and roof steel deck. Calculating the capacity of the roof steel deck was held and established, that capacity depends on plate buckling in the local support area. The support is the flange of canal girder with 0,078 inch thick. The damaging of upper deck was caused by reducing of support area. The reducing of support area was achieved by deflection of the flange of the canal girder. The value of this deflection depends on thick of canal girder. Thus the damage of the composite roof system was located near the roof area with increasing snow load. For this reason such composite roof system with 0,078 inch thick of canal girder are not allowed in roof area with increasing snow load.
Keywords.Composite roof system, steel deck, damage.
