Abstract
In this paper, the equation of the middle surface of a simply-supported truncated hip roof is established by means of the local coordinate system and generalized functions—sign function and step function. Then, the nonlinear analysis for this simply-supported roof subjected to uniform load is given by using the nonlinear theory of a 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 combined folded plate roof of the same dimensions.
