| Summary |
As membra.ne structures can keep their shapes only through in-plane stress, determination of the objective shapes of membrane structures has to be carried out appropriately by considering physical conditions. BesidesEproposal of the cutting pattern of membrane materials is also important in order to avoid unexpected wrinkling or creep deformation which itself can also cause the wrinkling after certain period passed from the initial introduction of prestressing. In this paperEa new approach for determination of the cutting pattern of membrane structures is proposed where the equilibrium state after deformation is simultaneously considered together with the configuration of the cutting pattern as the state of pre-deformation. Utilizing SQP technique for optimization processEthe finite element analysis is performed for several examples Ewhere effectiveness of proposed method is clearly shown.
