| 摘 要： | 采用双模量线性约束模型考虑芯板对面板的受压和粘结约束作用,运用能量法分析了面内压力作用下钢—混凝土组合墙板中面板的单面接触屈曲问题。为了解决MATLAB优化函数非全局优化问题,编写了二次搜索极小值函数,实现了对目标函数的全局优化,利用MATLAB的符号运算和优化工具箱求得了不同约束情况下的屈曲系数。通过与已有成果进行对比,验证了所用方法的有效性。 |

| Abstract: | The bimodulus constraint model is applied to simulate the constraint of inner materials under pressure.To analyze the unilateral contact compressive buckling of steel skin sheet in steel-concrete composite wall,the energy method is adopted.The function for searching secondary minimum is programed to solve the non-global optimization problem.So the global optimization of the objective function is achieved.The buckling factor values under different circumstances are obtained by using the symbolic computation ... |
