 In this paper is presented a method of finding the. reactive moments distributed along the clamped edges of a rectangular plate by means of double sine series. Plate with two opposite edges clamped and the other two opposite edges simply supported, and plate with all four edges fixed are used as illustrative examples; the load being uniformly disdributed. The results we obtained are certainly exactly the same that we had obtained by using the method of superposition. However, the method by the double series... In this paper is presented a method of finding the. reactive moments distributed along the clamped edges of a rectangular plate by means of double sine series. Plate with two opposite edges clamped and the other two opposite edges simply supported, and plate with all four edges fixed are used as illustrative examples; the load being uniformly disdributed. The results we obtained are certainly exactly the same that we had obtained by using the method of superposition. However, the method by the double series has its advantages, when the loads acting on the plate are discontinous. Besides our method can be easily extended for solving the reactive moments of clamped edges of plates on the elastic foundation and under the combined action of lateral load and uniform compression or tension.  本文提供以双重三角级数解作用于矩形板的固定边的弯矩，以代替通常所用的叠加法。这样，一方面可以不必去解板的弯曲面的偏微分方程；另一方面，当作用于板的荷重并不连续而应用叠加法成为很困难时（因计算一四边简支的板在不连续的荷重作用下的弯曲面实非易事），这双重三角级数的解法仍不失为一有效的途径。 对于在计算上更为困难的一类问题，例如在弹性基础上的矩形板，及垂直有重与作用于板的中间面的拉力或压力共同作用的板，我们仍可用双重三角级数以计算作用于固定边的弯矩。 并且，由于能计算级数的极限和的值，所以上述这方法在运算上很为简单。  By dividing a folded plate into many "isolated" single plates with equivalent edges, the theory of thin plate bent from sidesway can be used to obtain the flexibility matrix of the edges, the displacement and internal stress due to external loads and those carried over from adjacent plates, and the behaviour of thefolded plate under load can be found by superposition.Compared with various methods currently used, this one provides a comprehensive understanding of the behaviour of...
