對于加筋板中加強筋腹板的局部屈曲，則用解析法推導出筋的腹板的撓度方程及其邊界條件，求解相應的方程，從而計算出腹板的局部屈曲應力。 -
Local buckling capacity of steel composite beam subjected to combined bending, shear and patch loading is one of key problem in steel structures design. the computational formula for local stability of web was based on the assumption of infinite - elastic perfect plates in the steel structures design code ( gbj17 - 88 ). but in the revised code ( gb50017 - 2003 ), this formula was made big change with reference to british code ( bs5950, partl ) and australian code ( as4100 ), the related research result of our country was included as well. in the modified formula, influence of early geometric imperfection and elastic - plastic buckling stage were considered, which is compatible with both actual circumstance of engineering and the strength formula of beams under bending stresses ( considering partial plasticity of the section ). in this paper, the preceding problem is deeply analyzed and studied, considering the effects of various geometric parameters and stress combinations on buckling critical stress of web, the revised local buckling correlative formula for transverse and longituded stiffened web panels under combined stresses is analyzed and verified by finite element method
組合鋼梁腹板在彎、剪及局壓復合應力作用下的局部屈曲承載能力是鋼結構設計中需考慮的問題，新的《鋼結構設計規范》 （ gb50017 ? 2003 ）對此部分內容作了較大改動，原規范中關于腹板局部穩定的計算公式是基於無限彈性的完善板假定；新的規范則參考了英國規范（ bs5950 part1 ）及澳大利亞規范（ as4100 ）並結合我國相關研究成果，考慮了屈曲進入彈塑性階段以及初始幾何缺陷的影響。這不僅與工程實際情況相符，而且也與鋼梁在彎曲應力作用下允許截面部分進入塑性的計算公式相協調。 -
The discrete stiffener solution and orthotropic plate solution are used for analyzing the buckling behavior of intermediately stiffened plates theoretically in this paper. thus, closed - form solution of critical buckling stress and required adequate stiffening rigidity of the stiffener is obtained
本文分別用分離加勁肋法和各向異性板法對縱向中間加勁板件的屈曲性能進行了理論分析，得到了屈曲應力和理論充分加勁剛度解析表達式。 -
