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。 -

At first, the mechanical model of joint is discussed, and the constitutive relation of the rough joint, especially the bolt - supported joint, is given. then bedding slide of bedding stratified rock slope is studied adopting limit equilibrium method, and a formula of stability is brought forward. at last, the bedding stratified rock slope ' s buckling deformation and failure mechanism and its evaluating method of stability is investigated, a corresponding mechanics model is established, then detail research to this failure mode is made in theory combining the energy law and elastic stability theory of plate and beam, and an analytical solution of the yielding curve is educed from this model
文中首先對結構面的力學模型進行了一定的探討，提出了粗糙結構面尤其是加錨結構面的本構關系；然後採用極限平衡法，研究了順向層狀巖質邊坡的順層滑動失穩，提出了其穩定性計算公式；最後，結合能量定律和彈性板梁穩定理論，探討了工程中常見的順向層狀巖體邊坡潰屈失穩時的破壞機理、變形規律和穩定性定量評價方法，建立了相應的力學模型，求出了其相應的解析解，並提出了臨界坡長與最大彎曲位置的確定方法。 -
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。 -
The concept of the longitudinal strength of ship hulls has changed and advanced greatly as the study on the failure mechanism of the hull is getting deep. by taking account the failure modes of yielding, buckling and their combination, as well as the non - linear interactions between structural members, the ultimate longitudinal bending moment is defined by the moment corresponding to the point with zero slope on the moment - curvature curve of the ship hull
但隨著對船舶破壞機理的認識和研究發現，在研究船體的總縱極限強度時，必須考慮構件的屈曲、屈服等各種可能的破壞模式，要考慮受壓構件屈曲后及崩潰后的非線性性能的影響，要考慮組成船體的各個構件發生破壞的漸進性質和相互作用等。 -
Moreover, the detailed calculation and contrastive analysis are carried out by using the software ansys. theoretical calculation and testing results show that adopting the connection construction with a hole on the web can alleviate the stress state greatly and transform the failure mode of the connection from brittle fracture to local buckling damage on beam, reduces the possibility of brittle fracture by welding and improve the ductility performance of connection to a great extent
結果表明，採用腹板開孔的節點形式，可以使梁的塑性鉸位置由梁根部向中部偏移，達到了有效控制塑性鉸位置的目的;同時，採用這種節點構造可以改變節點附近的梁截面應力分佈狀態，降低了節點脆性破壞的可能性，使節點的破壞模式從脆性破壞轉變為梁的局部屈曲破壞，很大程度上改善了結構的延性。 -
Several numerical results of elastic restrainted thin - walled members involving bending, torsional, and flexural - torsional elastic buckling failure modes are presented to demonstrate the accuracy, efficiency, and versatility of the method. comparisons with published analjtical and semi - anaiftical solutions are made using some of the obtained results
