Treated in this work is the optimality of flexureless orthogonal archgrids. Various features of fully stressed arches and archgrids are highlighted and an efficient and simple iterative method for obtaining the optimal solution is proposed. Considering the load proportions carried by arches as independent variables, the optimality of the archgrid is ensured by imposing the conditions of equal elevation at nodal intersections and individual optimality of component arches. Computational effort, is reduced by using a simple updating procedure during repetitive calculations. The convergence of the solution is aptly tested by the convergence of elevations and compressive forces in arches. It is shown that the optimal solutions for some skew archgrid systems can be obtained by solving equivalent orthogonal archgrids. |
