The Deflection of Orthotropic Saddle Membrane under the Snow Load

Article Preview

Abstract:

This paper reviews the research on the deflection of orthotropic saddle membrane under the external snow load. First the authors build the model of orthotropic saddle membrane under the snow load. Second we deduce the equations set of the saddle membrane which has the effect of pretension. Then we solve the equations set with the perturbation method. So we obtain the relational expression between the maximum deflection of the membrane’s centre point and the external load. At last, suppose that the load was determinate, the authors analyze the change of the deflection of the centre point of the membrane with different pretensions, side lengths and other parameters.
