摘　　要：根据文献［３］的理论，按文献［１，２］同样的方法，算出雁形板及Ｖ形折板纵向水平集中荷载的应力系数。同时，还用有限元法，对这种屋盖受横向水平集中荷载作用的情况进行了计算，计算结果表明，雁形板屋盖与Ｖ形折板屋盖相比，更能满足水平面内刚度无限大的假设，且其空间整体工作性能优于Ｖ型折板屋盖。With the help of theory in ref. and the method in ref.,the stress coefficients for the bird shape & V shape folded plates under the longitudinal and horizontal concentrated load are calculated.Besides,the distribution of stresses and displacements of these structures under the transverse horizontal concentrated loads are analyzed using the Finite Element Method.The numerical results indicate that the bird shape plate roof can be satisfied with the hypothesis of “infinite inplane rigidity” and the space behaviour of the bird shape plate roof prevails over the V shape folded plate roof.
