The force method of structural analysis is used to compute the independent states of self-stress of the fully deployed structure, and also to simulate the deployment motion. I have developed a sensitivity analysis based on the force method to optimise the stiffness of a pantographic deployable structure, subject to weight and buckling constraints. In addition, I have developed a shape adjustment method to correct for manufacturing errors and thermally induced deformation by altering the length of some structural members. High shape accuracy is a general requirement for mesh reflectors.
