说明：  本软件基于MATLAB平台，针对矩形开口甲板的单侧强框架加筋板结构，使用二分法迭代求解非线性相似准则对应的控制方程，得到考虑非线性相似问题的简化加筋板几何参数，根据简化加筋板模型的试验结果计算原矩形开口甲板的极限承载力，并开发出简单实用的用户操作界面，可有效降低原大尺寸结构非线性设计过程中大量几何参数计算的工作量，并可直观高效地获得原型矩形开口甲板的极限承载力。
(Based on the MATLAB platform, this software uses the dichotomy method to iteratively solve the governing equations corresponding to the nonlinear similarity criterion for the single-side stiffened plate structure with rectangular open deck. The geometric parameters of the simplified stiffened plate considering the nonlinear similarity problem are obtained. According to the experimental results of the simplified stiffened plate model, the original rectangular open deck is calculated. The ultimate bearing capacity of the original large-scale structure can be reduced effectively by developing a simple and practical user interface, and the ultimate bearing capacity of the prototype rectangular open deck can be obtained intuitively and efficiently.)
