摘要
基于有限元分析方法对用钢量相同的折线形、梯形、正弦曲线形波纹腹板钢梁进行了弹性的特征值屈曲分析,综合考虑了腹板厚度、钢梁高度、波纹周期等几何参数变化的影响,对比分析了3种波纹腹板钢梁的弹性整体稳定临界荷载。分析结果表明,用钢量相同的3种波纹腹板钢梁,折线形波纹腹板钢梁弹性整体稳定承载力较高。
Based on finite element analysis software,the beams with folded,trapezoidal and sinusoidal corrugated web steel under the same amount of steel were analysis by the eigenvalue buckling.Considering the effect of different geometric parameters such as web thickness, girder height, corrugation cycle.The overall buckling capability of the girder with three different types of corrugated web was compared.The results show that,the overall buckling capability of folded corrugated web steel beams is higher than that of the others.
