Abstract

In this paper, the equation of the middle surface of a simply-supported hip-truncated combined parabolical cylinder roof is established by means of the local inclined coordinate system and step function. Then,the nonlinear analysis for this simply-supported roof subjected to uniform load and point loads is given by using the nonlinear theory of shallow shell and the nonlinear Galerkin method. Finally, an illustrative example of this roof is presented. This example indicates that the largest stress of this roof is much less than that of the hip-truncated four pitch roof of same dimensions.
