DESIGN METHOD FOR STEEL BEAM
PROBLEM TO BE SOLVED: To provide a highly accurate design method for a steel beam, employing an evaluation formula for durability against lateral buckling that uses two moment correction coefficients appropriate for torsional conditions.SOLUTION: In the evaluation formula for durability against elastic lateral buckling Mfor a steel beam, resistance force by Wagner torsion and resistance force by Saint-Venant torsion are multiplied respectively by moment correction coefficients Cand Cfor calculating the durability against elastic lateral buckling M. Thus, a design method is provided for an H sectional beam having both ends 1a connected rigidly to a column 2 and an upper flange 1A fastened to a floor slab 4 and others with a shear connector, that is, a steel beam that prevents lateral buckling of a steel beam 1 with which lateral movement of the upper flange 1A is restricted.SELECTED DRAWING: Figure 1
【課題】ねじりの条件に応じた２つのモーメント修正係数を使用した横座屈耐力の評価式を用いることで、高い精度で鉄骨梁を設計することができる。【解決手段】前記鉄骨梁の弾性横座屈耐力Ｍｅの評価式において、ワグナーねじりによる抵抗力、およびサン・ブナンねじりによる抵抗力に、それぞれ別のモーメント修正係数Ｃ１およびＣ２を乗じることで、弾性横座屈耐力Ｍｅを算出することで、両端部１ａが柱２に剛接合され、上フランジ１Ａがシヤコネクタによって床スラブ４などに緊結されているＨ形断面梁、すなわち上フランジ１Ａの横移動が拘束された鉄骨梁１の横座屈を防止するための鉄骨梁の設計方法を提供する。【選択図】図１
