梁柱腹板屈曲时门式刚架极限承载力的分析

Analysis on the gate rigid frame limited bearing when the beam-column web bends

运用有限元分析软件ANSYS,对梁柱腹板屈曲时门式刚架的极限承载力进行了分析,研究了不同参数的变化对刚架极限承载力的影响,得出了增加腹板厚度、腹板高度、斜梁坡度及高跨比,可以提高刚架极限承载力的结论。

Using the finite dement analysis ,software ANSYS, it analyses the gate rigid frame limited bearing when the beam-column web bends, researches the affection of different parameter to the limited bearing of gate rigid frame, deduces the conclusion that it can increase the limited bearing of gate rigid frame of increasing the thickness of web, the height of web, the grade of oblique beam and the ratio of height and span.
