STEEL BEAM WITH FLOOR SLAB AND DESIGN METHOD THEREOF

To provide a steel beam with floor slab, which can ensure sufficient deformability by restricting a structural out-of-plane deformation of an upper flange of the steel beam due to lateral buckling even at a place where the floor slab is located at a position higher than that of the steel beam, and a...

description	To provide a steel beam with floor slab, which can ensure sufficient deformability by restricting a structural out-of-plane deformation of an upper flange of the steel beam due to lateral buckling even at a place where the floor slab is located at a position higher than that of the steel beam, and a design method thereof.SOLUTION: A steel beam with floor slab 1 of the present invention has an H-cross-section steel beam 9 and a concrete floor slab 11 that is jointed to the upper part of the steel beam 9. The steel beam with floor slab 1 has a flange part 13 and a steel member 17 that is joined along the entire length of an upper flange 7 of the steel beam 9 and satisfies the following formula (1) so that the flange part 13 is disposed above the upper flange 7 of the steel beam 9. The concrete floor slab 11 is joined through headed studs 19 disposed on the flange part 13 of the steel member 17. TJ≥0.035×bJf...(1), where TJ is the torsion coefficient of the steel member, and bJf is the torsion coefficient of the upper flange of the steel beam.SELECTED DRAWING: Figure 1 【課題】床スラブが鉄骨梁に対して高い位置にある場所であっても、横座屈による鉄骨梁の上フランジの構面外変形を拘束して十分な変形能力を確保できる床スラブ付き鉄骨梁およびその設計方法を提供する。【解決手段】本発明に係る床スラブ付き鉄骨梁１は、Ｈ形断面の鉄骨梁９と、鉄骨梁９の上部に接合されたコンクリート床スラブ１１とを有する床スラブ付き鉄骨梁１であって、フランジ部１３を有し、フランジ部１３が鉄骨梁９の上フランジ７の上方に配置されるように、鉄骨梁９の上フランジ７の全長に亘って接合されると共に下式（１）を満たす鋼部材１７を有し、コンクリート床スラブ１１が鋼部材１７のフランジ部１３に配設された頭付きスタッド１９を介して接合されていることを特徴とするものである。TJ≧0.035×bJf・・・(1)ここで、TJ：鋼部材のねじり定数bJf：鉄骨梁の上フランジのねじり定数【選択図】図１
