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。 -

Accounting for the effects of imperfection and large displacement of arch, an approach for the stability analysis of arch bridge is presented ， and a program is developed to predict the nonlinear buckling of arch the elastic lateral stability of the jiefang arch bridge in guangzhou during the construction phases and operating periods after its completion is analyzed the results show that the effects of initial deflection and large displacements on the critical load of lateral stability are significant, and that once the initial deflection and large displacement are taken into account, the values of the safety factor are smaller than those obtained by linear buckling analysis
考慮拱肋初始撓度等缺陷的影響，採用桿系結構大位移分析的有限元方法，建立了拱橋非線性穩定的計算方法，並編制了相應的計算程序文中計算了解放大橋鋼管混凝土拱橋在施工階段及成橋后運營期間的彈性側傾穩定結果表明：考慮拱肋初始撓度和結構大位移影響后，拱橋的非線性側傾穩定安全系數比按線性穩定計算值低
