摘要
本文首先利用阶跃函数和斜坐标系，建立了传统组合抛物面屋盖的壳面方程，然后应用扁壳理论和Ｎａｖｉｅｒ法，导出了传统组合抛物面屋盖的内力和挠度的计算公式，文末给出一算例。
Abstract In this paper, the curved surface equation of the traditional combined parabolical roof is established by means of step function and the inclined coordinates. And then, the calculating formulas of the internal force and deflection of the roof are derived from the theory of shallow shell and Navier method. Finally, a numerical example is given.
