The ship ' s hull is a thin - walled box girder structure composed of stiffened panels. the overall failure of a ship hull girder is normally governed by buckling and plastic collapse of the deck, bottom, or sometimes the side shell stiffened panels. therefore, the analysis of buckling and ultimate strength of ship panels in deck, boltom, and side shells is very important and necessary for the safety assessment of ship structure. in stiffened panels, local buckling and collapse of plating between stiffeners is a basic failure mode, and thus it would also very important to evaluate the buckling and ultimate strength interaction of plate elements under combined loads
船體梁的總體失效通常取決于甲板、船底板,有時候是舷側加筋板的屈曲和塑性破壞。因此,對于衡量船體結構的安全性而言,對甲板、底板、舷側板進行屈曲和極限強度分析是十分重要且必須的。對于加筋板而言,加強筋間的板格之局部屈曲和失效是最基本的失效模式。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。The author analyses the tripping of stiffener and three patterns of panel ' s invalidation, so to get the curve of stress - strain of panel. this step is the core of the thesis
本文從理論入手,分析了加筋板單元中加強筋的側傾屈曲,然後根據加筋板的三種破壞模式,得到單元的應力應變關系曲線,這是本文的重點與難點。The test study of the brick wall cement mortar reinforced with steel mesh indicates : when the consolidated brick wall fail in bending - shear, its ultimate horizontal load and drift stiffness respectively is 1. 5 and 2 times bigger than that of brick wall
試驗表明,經鋼筋網水泥砂漿面層加固的墻體;在發生彎剪破壞時,極限水平荷載可以達到原墻抗剪強度的1 . 5倍以上,抗側剛度可以達到原墻體的2倍以上,剛度的提高大於強度的提高。Bearing capacity and displacement are two main problems in the application of geotechnical engineering. based on a series of pull - out tests using three kinds of paper and a sort of window screening as geogrid, twenty - seven in limit and several in working - stress geogrid - reinforced slope model tests designed through orthogonal principle have been conducted to have obtained the relationship between the bearing capacity and four factors ( i. e. reinforcement, angle of reinforced slope, the designed - length of reinforcement and the distance between layers of reinforcement ). the law of slope lateral ( horizontal ) displacement versus to the height of slope vary with external - load was derived from the model test data, and the main factor affecting the lateral and vertical displacement of geogrid - reinforced slope was obtained through analysis
承載力(強度)和變形是巖土工程應用領域的兩大主要問題,本文以紙和窗紗布模擬加筋土邊坡的土工格柵,在一系列拉拔試驗的基礎上,以正交設計理論分別安排27個極限應力狀態和若干個工作應力狀態加筋土邊坡模型試驗,並以模型試驗獲得的數據為依據,採用誤差、極差及回歸分析方法,探討了加筋土邊坡承載力與筋類、筋長、層間距、坡角4因素的相關關系,獲得了在外荷載作用下加筋土邊坡的側向位移隨坡高的變化規律(並進行了定性解釋)和坡頂的豎向位移特性,並分析其主要控制因素。Since the overall failure of a ship hull is normally governed by buckling and plastic collapse of the deck, bottom or sometimes the side shell stiffened panels, it is of crucial importance to accurately calculate the ultimate strength of stiffened panels in deck, bottom and side shell for more advanced structural design of ship structures
由於船體梁的總體破壞通常由甲板、底板或者舷側加筋板的屈曲或塑性破壞控制,因此在船舶結構設計中準確地計算甲板、底板或舷側加筋板的極限強度就顯得尤為重要。In the analysis of the elastic tripping of the stiffener, the critical stress under this mode of failure is derived by using the energy method and the principle of least potential energy. in the analysis of the elastic overall buckling of stiffened plates, attention is focused on global buckling, and local buckling effects are neglected
對于加筋板中筋的側傾失穩,則通過能量法推導加強筋側傾失穩時的總勢能泛函,利用最小勢能原理求解出此失穩模式下的臨界應力。Several types of buckling mode and several types of collapse mode for the stiffened panels are mostly analyzed. it is emphasized on the influence of position of loading plane on the ultimate strength of stiffened panels and numerical calculation of stiffener tripping. at last the interaction of ultimate strength for stiffened panels combined different loads is discussed
