在对连续加劲铝板屈曲和极限强度的敏感性研究基础之上,对压力作用下的铝板进行了深入研究。开发了一个经验公式,用于预测海洋工程中采用焊接加劲铝板在平面内轴压和各种侧向压力作用下的极限抗压强度。极限抗压强度的计算利用了一些的铝板敏感性分析的相关数据,推导出来的公式中含有两个参数,分别是板长细比和柱(加劲肋)长细比。推导过程中也用到了回归分析。公式考虑了焊接对初始缺陷和热影响区的影响。 Based on the research on the sensitivity of buckling and ultimate strength of continuously stiffened aluminum plates, the aluminum plate subjected to pressure is studied deeply. An empirical formula has been developed to predict the ultimate compressive strength of offshore engineering using axial stiffeners and various lateral pressures of welded stiffened aluminum plates. The calculation of ultimate compressive strength takes advantage of some relevant data from the sensitivity analysis of the aluminum plate. The derived formula contains two parameters: the slenderness of the plate and the slenderness ratio of the column (stiffener). The derivation process also used regression analysis. The formula takes into account the effect of welding on the initial defect and the heat affected zone.
