摘　　要：利用有限元软件HyperMesh,采用等效结构应力法研究支座加劲肋宽度及其位置对正弦波纹腹板梁疲劳性能的影响。结果表明,当支座加劲肋宽度增加至加劲肋与腹板接触时,并且加劲肋位于正弦波纹腹板的波峰处时,正弦波纹腹板梁的疲劳性能最佳。Using the finite element software HyperMesh and equivalent structural stress method, the effects of stiffening rib width and position on the fatigue performance of sinusoidal corrugated web beam were studied. The results show that when the width of the stiffening rib is increased so much that the stiffening rib touches the web and the stiffening rib is located in the peak （or valley） of the si- nusoidal web beam, the fatigue performance of the beam is the best.
