Using the Method of Unit Moment of Couple to Analyze Continuous Rectangular Plates Supported on Elastic Foundation with Complicated Boundary Condition

本文提出了用单位力偶矩法分析弹性地基上和具有复杂边界条件的连续矩形板,用它推导弹性地基上三弯矩方程和计算侧面具有固定边的连续矩形板都很简单.单位力偶矩法和单位荷裁法联合应用可解决具有自由边和自由角点连续矩形板的计算问题.

In this paper a method is put forward to analyze continuous rectangular plates supported on elastic foundation with complicated boundary condition by using the method of unit moment couple.The con- tinuous rectangular plates with middle point supports,corner point supports and free boundary are cal- culated and the general calculating method is provided to analyze the plates with various complicated boundary conditions.The results are compared with those of Zhang Fufan and S.P.Timoshenko,and they are the same
