| Abstract: | The concept of elastic support is defined in this paper,for the real contacts and constraints between structural bars,based on the concept of conventional support in structural mechanics.Two basic systems of elastic supports are established,with two feedback basic equations,and the basic formulas of the rod end constraint stiffness in both directions are obtained.The elastic support analysis method of structure mechanics is then formulated.The finite element equations for the elastic support analysis method... |
