Structural behaviour of composite slim floor frames in fire conditions
AbstractThe structural behaviour of the composite slim floor frame as a whole in fire conditions has been investigated. Both the deformation behaviour of the structural members and the mechanical interaction between the members were studied. The additional lateral deformation of the side-column caused by the thermal expansion and the catenary action in the beam in the different fire phase was highlighted. The moment variation in the head of the columns during fire and the variation of the axial force in the heated beam were also investigated. A comparison between the deformation behaviour of the heated beam in the plane frame and the spatial frame indicated the excellent effects of the composite floor slab on the stability of the frame structures in fire.
