Abstract
A series of papers regarding the form finding of conic membrane structures with fixed stress ratio not equal to unity reported numerical instabilities in the convergence properties of the iterative procedures employed when the structure was not axisymmetric. This paper will find a theoretical basis for this instability and propose possible methods to obtain approximate solutions to the problem.
