Cfrp加固梁在承受彎曲荷載時的破壞是鋼筋屈服后碳纖維斷裂和鋼筋屈服后混凝土壓碎。本文通過應變相容方法和對破壞機理的定義,由給定的cfrp橫截面積預測加固梁的極限彎曲強度;或者相反,在已知加固梁的極限彎曲強度時可以求出所需的cfrp橫截面積。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。In this part, it is also found that the equivalent prismatic column, which is obtained based on the equal elastic critical load as the non - prismatic member, is not actually equivalent to the tapered column in inelastic stability, and the latter has higher load carrying capacity. finally, the behavior of tapered beam - column acted by combined axial load and transverse load has been investigated. a bending - thrust interaction curve is established which is similar to the ones for the design of prismatic members
三是研究了楔形變截面懸臂構件在大端固定,小端同時承受橫向及軸向荷載共同作用下的強度和彎矩平面內的穩定,同時參考等截面構件的設計公式,得到了用大端截面來表示的軸力p與彎矩m的之間的相關關系。Standard test method for compressive strength of soil - cement using portions of beams broken in flexure modified cube method
用橫梁彎曲斷裂部分測定摻土水泥抗壓強度的標準試驗方法Then, a step - by - step increase of vertical curvature is applied to the hull girder assuming that the plane cross section remains plane. at each incremental step, the stress of the cross section is evaluated using the average stress - strain curves of the elements as well as the incremental bending moment due to the curvature increment. performing sample calculations on existing girder models tests under pure bending, the rationality of the proposed method was examined
假設船體橫向框架材足夠強,因而板架的整體破壞不會發生;基於梁?柱理論、理想彈塑性假設、平面假設,建立了拉伸和壓縮加筋板單元的平均應力?應變關系曲線,應用船體結構總縱極限強度的簡化逐步破壞分析方法計算船體總縱極限彎矩,並據此開發了計算程序sus 。Here we obtain concepts of fracture mechanincs, the required cfrp cross - sectional area to achieve a targeted resisting moment of rehabilitated flexureal element
