STEEL BEAM WITH FLOOR SLAB
To provide a steel beam with a floor slab preventing a stud with head from being pulled out from the floor slab by a torsional deformation of the steel beam due to a horizontal buckling even when the floor slab is attached only in one direction of a beam material shaft orthogonal direction to restrict a horizontal buckling deformation restraining effect of the floor slab from being lost and its design method.SOLUTION: In a steel beam 1 with the floor slab according to the invention, both ends are rigidly connected to a pillar and the floor slab 11 is connected to an upper flange 7 of the steel beam via a stud with head 13 as a connection member, and the floor slab 11 is continuous on one side of the beam material shaft orthogonal direction and is an edge part without being continuous on other side and ΣsAc which is a total amount of effective projection area of the stud with head 13 arranged in the range of at least 20% of a beam length from a beam end when being pulled out satisfies the formula below, ΣsAc≥1.2×bN×bAc,,,(1) however,bAc:effective projection area.bN:a number of studs with head.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
