［摘要］采用有限元分析方法，通过改变构件的跨度、腹板高度、翼缘宽度和厚度等几何参数，系统研究了波形腹板H型钢梁的抗剪性能，得到了不同的屈曲模态，并且通过与具有相同几何尺寸和荷载边界条件的普通H型钢梁的比较，得到了结构抗剪承载力受初始缺陷影响较小的结论。通过理论分析，得到了一个可以用来指导设计的抗剪承载力计算公式，具有较大的推广价值。

Abstract:By changing the geometric parameters such as span, web height, flange width and thickness, the finite element analysis method was mainly used to systematically study the shearing behavior, and different buckling modes were got. By comparing with the common H-shaped steel beam with the same geometry and loading boundary conditions, the result that the corrugated web H-shaped steel beam has a better shearing strength was got.Through theoretical analysis, a shearing capacity formula was advised to guide the design, which has a great promotional value.

Keywords:corrugated web; shear capacity; finite element analysis
