An Experimental Study on the Behavior of Full-Scale Frames With Slim Floor Slab Construction Under Furnace Loading
Yuli Dong, Kuldeep Prasad
In recent years, increasing interest has been shown in developing and designing slim floor systems in steel-framed buildings. This paper describes the results of a furnace test conducted on two full-scale composite steel frames with slim floor slab construction to understand their performance under fire loading. In one frame, the beam-to-column connections were protected, while in the second frame, the columns as well as the beam-to-column connections were protected. During test, the furnace temperature, steel and concrete temperature as well as the horizontal and vertical displacements were recorded. The complete deformation process of the test frame observed during the heating phase and the cooling phase, including failure of the frame is described in this paper. A comparison of the data obtained from the two tests indicates that the fire resistance of a composite beam is significantly better than that of a steel column. Fire resistance of composite frames with slim floor slabs is compared with data on conventional floor slab. Results indicate that the fire resistance rating of frames constructed with slim floor slabs is at least as good as that of frames with conventional floor slab construction.
