【摘要】：對(duì)兩種雙軸對(duì)稱工字型懸臂鋼梁——懸臂端無(wú)封口梁和懸臂端有封口梁,在組合荷載作用下的穩(wěn)定性進(jìn)行了研究,分析表明:對(duì)于無(wú)封口梁的雙軸對(duì)稱工字型懸臂鋼梁,可以按GB 50017—2003《鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范》方法進(jìn)行整體穩(wěn)定計(jì)算,精度能夠滿足工程設(shè)計(jì)要求;而對(duì)于有封口梁的雙軸對(duì)稱工字型懸臂鋼梁,按GB 50017—2003方法進(jìn)行穩(wěn)定計(jì)算,誤差較大,該方法欠妥。分析給出了有封口梁的雙軸對(duì)稱工字型懸臂鋼梁的穩(wěn)定計(jì)算式,可供工程設(shè)計(jì)參考。
[Abstract]:The stability of two kinds of double axisymmetric I-shaped cantilever steel beams, the cantilever end unsealed beam and the cantilever end sealed beam, under the combined load is studied in this paper. The analysis shows that the overall stability of double axisymmetric I-shaped cantilever beams with unsealed beams can be calculated according to GB50017-2003 Code for Design of Steel structures. The precision can meet the requirements of engineering design; However, for the double axisymmetric I-shaped cantilever beam with sealing beam, the stability calculation is carried out according to GB50017-2003 method, and the error is large. The stability calculation formula of double axisymmetric I-shaped cantilever steel beam with seal beam is given, which can be used as a reference for engineering design.
