碩士 === 國立交通大學 === 土木工程研究所 === 81 === This paper presents the relations between forces and displacements of beams on the elastic foundation, that is, the stiffness matrix. The approach to the formulation of the stiffness matrix is using the method of structural matrix, which is frequently used for analyzing many structures. The process of formulation is on the assumption that the soil medium is simulated as the uncoupled linear springs such that it simplifies the mathematical calculations. Except for the formulation of previous matrix, presented also analyze some problems about the frame structure, the fixed-end moment, and the elastic stability. Furthermore, presented discusses some topics about above problems and makes suggestions about them.
