Abstract: Based on the teaching practice of structural mechanics, the concepts of geometric structural analysis are used for determining the internal forces of statically determinate structures, with the kinematical method to construct the influence lines of beam structures, and with the principle of virtual work to calculate the reaction forces of supports of statically determinate structures; The differences and the relations among the degrees of freedom, the computational degrees of freedom, the structural dynamic computational degrees of freedom and the degrees of freedom for stability problems are analyzed; The characteristics and the applications of the force method, the displacement method are reviewed. The method of applying the multimedia, the experiment and the numerical simulation in teaching the structural mechanics is discussed. The intrinsic relationship in the structural mechanics, some confusing concepts and the characteristics of various methods, are clarified.

Key words: structural mechanics, teaching method, teaching practice
