STEEL BEAM WITH FLOOR SLAB AND DESIGN METHOD THEREFOR
To provide a steel beam with a floor slab which, even in the case where the floor slab is provided in only one direction of the beam material axis orthogonal direction, can prevent studs with heads from drawing out from the floor slab due to torsional deformation of the steel beam caused by lateral buckling and make the lateral buckling deformation restraining effect of the floor slab not dissipate, and provide a design method therefor.SOLUTION: In a steel beam 1 with a floor slab according to the present invention, its both ends are rigidly jointed to a column; a floor slab 11 is bonded to an upper flange 7 of the steel beam through studs 13 with heads as joint members; and the floor slab 11 forms a marginal part by continuing to one side of the beam material axis orthogonal direction and not continuing to other side thereof. A total sum ΣAof the effective projected area when drawing out the studs 13 with heads satisfies the following formula (1): ΣA≥1.2×N×A, whereArepresents an effective projected area, andN represents the number of studs with heads, the studs 13 with heads disposed within the range of at least twenty percent of the beam length from the beam end.SELECTED DRAWING: Figure 1
【課題】梁材軸直交方向の一方向にのみ床スラブがついている場合であっても、横座屈による鉄骨梁のねじれ変形によって頭付きスタッドが床スラブから引き抜かれるのを防止して、床スラブの横座屈変形拘束効果が消失しないようにした床スラブ付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鉄骨梁１は、両端部が柱に剛接合されると共に、鉄骨梁の上フランジ７に接合部材としての頭付きスタッド１３を介して床スラブ１１が接合され、かつ床スラブ１１が梁材軸直交方向の一方側に連続し、他方側には連続することなく縁部となっているものであって、梁端から梁長さの少なくとも２割の範囲に配置される頭付きスタッド１３の引抜時の有効投影面積の合計ΣsAcが下式（１）を満たすことを特徴とするものである。ΣsAc≧1.2×bN×bAc・・・（１）但し、bAc：有効投影面積bN：頭付きスタッドの本数【選択図】 図１
