Abstract
An analytical study and the application of the rectangular plates with two adjacent sides fixed and other two sides free under triangularly distributed regional loads are shown in this paper. The Type-3 Fourier series analytical method proposed by Higashi, Y. and Komori, K. was developed here. A comparison study for the bending moments of the fixed sides of the rectangular plates was carried out with Finite Element Method (FEM). The rationality and the applicability of analytical results were estimated and discussed. The figures of the coefficients of the bending moments and the shearing forces on the fixed sides of the rectangular plates were presented for the designer.
