In the hogging condition, double bottom and the side shell remain the ultimate bucking strength, deck and upperwing tank remain the yield stress, and the other parts keep elasticity. then the key to calculate the ultimate strength of ship hull girders is to ascertain the ultimate bucking strength of the stiffened panels. in this regard, the developed formulation is designed to be more sophisticated than previous simplified theoretical method for calculating the ultimate strength of stiffened panels under combined in - plane bending and lateral pressure. fabricatio n - related initial imperfections ( initial deflections and residual stresses ) are included in the panel ultimate strength calculation as parameters of influence. all possible collapse modes involed in collapse of stiffened panels, including overall buckling collapse, column or beam - column type collapse, tripping of stiffeners and local bukling of stiffened web are considered
確定了船體梁整體破壞時的剖面應力分佈之後，關鍵在於確定板架的極限屈曲強度。本文充分考慮了在縱向彎曲、橫向壓力作用下加筋板可能發生的幾種破壞模式，即板架的整體屈曲破壞、樑柱形式的破壞、筋的側傾、腹板的屈曲並同時考慮了初始焊接殘余應力、初撓度的影響，使其更精確的計算加筋板的屈曲強度。對于加筋板中加強筋腹板的局部屈曲，採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。 -

（ 4 ）本文通過對矩形鋼管考慮和不考慮板組相關影響承載力的比較，得出了屈曲后矩形鋼管板組相關作用與翼緣、腹板寬度比b _ f / b _ w的關系，同時也得出板組相關性與板件寬厚比b _ f / t 、 b _ w / t的關系及規律。 -
Gabled frames are widely used in industry and civil engineering, it ' s web plates " local buckling calculated formula in the technical specification for steel - structure of one - storey light - weight buildings with gabled frames ( cecs102 : 98 ) are based on the rectangular plates " and did n ' t consider the interaction of the fringe plate. so, there are some different between the actual members and the prescript of the specification, and the post - buckling strength ' s calculated formula is based on the local buckling ' s, it must have some unreasonable
楔形門式剛架廣泛地應用於工業與民用建築中， 《門式剛架輕型房屋鋼結構技術規程》 （ cecs102 ： 98 ）中楔形腹板局部屈曲的計算公式來自矩形板，並且沒有考慮翼緣的相關作用，因此，規程中的規定與構件的實際工作狀況有一定的差異，且屈曲后強度的計算公式也是以局部屈曲系數為基礎的，勢必有其不合理性。 -
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。 -
