BUCKLING STRESS INTENSITY ESTIMATION DEVICE, BUCKLING STRESS INTENSITY ESTIMATION METHOD, AND BUCKLING STRESS INTENSITY ESTIMATION PROGRAM
To provide a buckling stress intensity estimation device for estimating a buckling stress intensity in consideration of coupled buckling of a web plate element and a flange plate element in H-section steel on which an axial force and a bending moment act.SOLUTION: A buckling stress intensity estimation device 50 estimates a buckling stress intensity with local buckling occurring in H-section steel on which an axial force and a bending moment act simultaneously around a z-axis extending in a plate thickness direction of a web plate element, and includes: a displacement estimation unit 52 that estimates out-of-plane displacement of the web plate element in the direction along the z-axis using a mathematical formula, and estimates out-of-plane displacement of a first flange plate element and a second flange plate element in the direction along the y-axis using mathematical formulas, respectively; and a stress intensity calculation unit 53 that obtains the buckling stress intensity of the H-section steel from the out-of-plane displacement based on the energy method.SELECTED DRAWING: Figure 2
【課題】軸力及び曲げモーメントが作用するＨ形鋼において、ウェブ板要素とフランジ板要素との連成座屈を考慮して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】座屈応力度の推定装置は、軸力、及びウェブ板要素の板厚方向に延びるｚ軸回りに曲げモーメントが同時に作用するＨ形鋼に局部座屈が生じるとき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、ウェブ板要素におけるｚ軸に沿う方向に向けた面外変位を数式により推定し、かつ、第１フランジ板要素、第２フランジ板要素におけるｙ軸に沿う方向に向けた面外変位を数式によりそれぞれ推定する変位推定部５２と、Ｈ形鋼の座屈応力度を、面外変位からエネルギー法に基づいて求める応力度算出部５３と、を備える。【選択図】図２
