FIREPROOF DESIGN METHOD OF FLOOR SLAB
To provide a fireproof design method of a floor slab for designing the floor slab by reflecting an experimental result of an experimental concrete floor slab confirmed to have a fireproof performance from a fireproof experiment.SOLUTION: A fireproof design method of a floor slab comprises the steps of: measuring an experimental deflection amount of an experimental floor slab 32 that can maintain fire resistance performance by supporting four sides of the experimental floor slab 32 reduced from a design floor slab 62, by experimental beams 34, loading a specified load on the experimental floor slab 32 and heating the same; calculating a span ratio as ratio between a span of a design beam 64 supporting the design floor slab 62 and a span of the experimental beam 34 supporting the experimental floor slab 32; specifying the specified deflection amount corresponding to the upper limit of a deflection amount of the design floor slab 62 by the experimental deflection amount from the span ratio; and estimating the design deflection amount of the design floor slab 62 in fire previously set. The fireproof design method of a floor slab designs the floor slab so that the design deflection amount is equal to or smaller than the specified deflection amount specified therein.SELECTED DRAWING: Figure 4
