| Abstract: | In this paper, Winkle Assumption is used to derive the differential equations of deflection curves for beams on the elastic foundation of under-ground architectural structures. Computational formulae of deflection "y", rotational angle "θ", bending moment "M", and shearing force "Q" of beams are derived respectively, they are corresponding to the section of beams on the elastic foundation under different loading conditions. Solutions of the fundamental equations are got by Initial Parameter Method, the computational expressions that got by this method can be used for most beams on the elastic foundation, and can yield satisfactory results. |
