| Abstract: | An approximate calculation method on elemental stiffness matrix for light-weight steel portal frame was presented in this paper. According to this method, fixed end moment could be calculated. So we can regard it as a calculation basis for designing computer programs by means of displacement of matrix, and also can provide conveniences for designers to check the data of the light-weight portal frame. |
