双曲扁壳的边缘支承构件,在中小跨壳体中一般作成抛物线双铰拱(图1)。目前关于这种壳体边拱简化计算的资料还不多。在一般计算中,往往按照图2的荷载形式,根据结构力学中所熟知的双铰拱的计算方法,求得拉杆的拉力及拱的内力。这种方法不仅非常麻烦,且仍属近似方法。它把壳体边缘剪力S的分布荷载形式化成 The edge support members of the hyperbolic flat shell are generally made into parabolic double hinged arches in the middle and small span shells (Figure 1). At present, there is not much information on the simplified calculation of such shell side arches. In general calculations, the pulling force of the tie rod and the internal force of the arch are often obtained in accordance with the calculation method of the double hinged arch, which is well known in structural mechanics, in accordance with the load form of FIG. 2 . This method is not only very cumbersome, but it is still an approximation. It forms the distributed load of the shear force S of the shell into a
