［摘要］采用有限元參數(shù)分析結合數(shù)學擬合的方法，以腹板高厚比為參變量，同時剔除腹板厚度的影響，研究沿主壓應力方向設置斜向加勁肋的H型鋼梁極限承載力與全截面塑性承載力的擬合關系。分析發(fā)現(xiàn)，適當厚度的斜向加勁肋可顯著提高鋼梁的抗剪承載力。

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
