ESTIMATION DEVICE, ESTIMATION METHOD, AND ESTIMATION PROGRAM OF BUCKLING STRESS INTENSITY
To provide an estimation device of buckling stress intensity, which estimates buckling stress intensity of an H-shaped section member receiving only a bending moment without convergence calculation.SOLUTION: An estimation device 50 of buckling stress intensity has a pair of flanges and a web, and estimates buckling stress intensity of an H-shaped section member on which only a bending moment acts around a reference axis extending in a plate thickness direction of the web as external force. The estimation device also includes an estimation section 52 for estimating the buckling stress intensity on the basis of a width-thickness ratio of the web in consideration of a buckling restraint effect on the web by the pair of flanges. The buckling restraint effect is represented by a first ratio as a ratio of a plate thickness center distance of the pair of flanges and each width of the pair of flanges and a second ratio as a ratio of each thickness of the pair of flanges and a thickness of the web.SELECTED DRAWING: Figure 2
【課題】曲げモーメントのみを受けるＨ形断面部材に対して、収斂計算を行うことなく座屈応力度を推定する座屈応力度の推定装置を提供する。【解決手段】一対のフランジ及びウェブを有し、外力として、ウェブの板厚方向に延びる基準軸回りに曲げモーメントのみが作用するＨ形断面部材の座屈応力度を推定する座屈応力度の推定装置５０であって、一対のフランジのウェブに対する座屈拘束効果を考慮して、ウェブの幅厚比に基づいて、座屈応力度を推定する推定部５２を備え、座屈拘束効果は、一対のフランジの板厚中心間距離と一対のフランジそれぞれの幅の比である第１比、及び一対のフランジそれぞれの厚さとウェブの厚さの比である第２比を用いて表される。【選択図】図２
