受纯弯载荷的箱型梁极限承载力试验中，涉及到材料非线性和几何非线性的耦合问题，而现阶段的模型箱型梁设计中，均未能考虑到几何非线性的影响，使得模型与原型的相似程度大大降低。本软件以纵骨架式箱型梁为研究对象，基于MATLAB平台，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模型箱型梁的剖面几何参数，根据模型箱型梁的试验结果计算原型箱型梁的极限弯矩，并开发出简洁的用户操作界面，直观方便，(The coupling problem of material nonlinearity and geometric nonlinearity is involved in the ultimate bearing capacity test of box girder subjected to pure bending load. However, the influence of geometric nonlinearity is not taken into account in the design of model box girder at present, which greatly reduces the similarity between model and prototype. Based on the MATLAB platform, the control equations corresponding to the nonlinear similarity criterion are solved iteratively by the dichotomy method. The section geometric parameters of the model box girder considering the nonlinear similarity problem are obtained. The ultimate bending moment of the prototype box girder is calculated according to the test results of the model box girder. Develop a simple user interface, intuitive and convenient.)
