［摘要］采用有限元参数分析结合数学拟合的方法，以腹板高厚比为参变量，同时剔除腹板厚度的影响，研究沿主压应力方向设置斜向加劲肋的H型钢梁极限承载力与全截面塑性承载力的拟合关系。分析发现，适当厚度的斜向加劲肋可显著提高钢梁的抗剪承载力。

Abstract: The fitting relationship between the ultimate bearing capacity and the total cross section plastic bearing capacity of H-shaped steel beam, whose web stiffened by oblique stiffener along the principal compressive stress direction, was studied applying finite element parameter analysis method combined with mathematical fitting, with the web′s height-thickness ratio as parameter variable, and with the impact of the web′s thickness eliminated. Its shear strength could be increased notably by setting proper thickness oblique stiffener, which is found by the analysis.

Keywords: oblique stiffener; parameter analysis; H-shaped steel beam; ultimate bearing capacity
