Analysis on the Parametric Design and Static Performance of the Hyperbolic Paraboloid Shells with Rectangular Projection

Abstract

This paper first used parametric design language APDL to establish three kind of the single hyperbolic paraboloid shell model with rectangular projection. The parametric design of the reticulated shell structure could be realized after inputting the span (S),rise (F),the grid number of each side (Kn),the warping rate (K),which provided great convenience for optimizing the structure and force analysis.Then through contrasting three structure schemes and different warping rate,it studied how they influence the mechanical properties of structure.And at last it got some conclusions with engineering significance.
