FIRE-RESISTING STRUCTURE
PROBLEM TO BE SOLVED: To provide a fire-resisting structure that reduces fire-resistive covering on a steel beam for sufficiently reducing a cost and curtailing a construction period, by appropriately evaluating an actual behavior of the steel beam exposed to fire heat input.SOLUTION: A fire-resisting structure 1 that applies the present invention is provided on a beam member of a building, and includes a plurality of column members 2, a plurality of girders 3 spanned on the column member 2, a beam 4 provided inside a space surrounded by the plurality of girders 3, and a floor slab 5 provided above the beam 4. The plurality of girders 3 includes a pair of orthogonal girders 31 provided roughly orthogonally to the beam 4, and a pair of parallel girders 32 provided roughly parallelly to the beam 4, and fire-resistive covering is applied on the first girder 3 of either the orthogonal girder 31 or the parallel girder 32. The fire-resistive covering applied on the second girder 3 of the orthogonal girder 31 or the parallel girder 32, as well as on the beam 4, is reduced more than the fire-resistive covering applied on the first girder 3 of either the orthogonal girder 31 or the parallel girder 32.SELECTED DRAWING: Figure 1
【課題】火災入熱を受ける鉄骨梁の実挙動を適切に評価して、鉄骨梁の耐火被覆の削減によるコスト削減及び工期短縮化を十分なものとした耐火構造を提供する。【解決手段】本発明を適用した耐火構造１は、建造物の梁部材に設けられるものであり、 複数の柱部材２と、柱部材２に架設される複数の大梁３と、複数の大梁３で取り囲んだ内側に設けられる小梁４と、小梁４の上方に設けられる床スラブ５とを備える。複数の大梁３は、小梁４に対して略直交させて設けられる一対の直交大梁３１と、小梁４に対して略平行に設けられる一対の平行大梁３２とを有して、直交大梁３１及び平行大梁３２の何れか一方の大梁３に耐火被覆が施される。直交大梁３１及び平行大梁３２の何れか他方となる大梁３並びに小梁４の耐火被覆は、直交大梁３１及び平行大梁３２の何れか一方となる大梁３に施された耐火被覆よりも削減された状態となる。【選択図】図１
