Optimal Design of Inelastic Cable Structures

Abstract : A nonlinear behaviour modelling of prestressed cable structures is firstly recalled, as dealt with in a previous paper and peculiar features of such structures are discussed. So, the important role played by pretension state is emphasized. Accordingly, optimum design problem is formulated assuming a cost function of pretension forces only. Optimality criterion is found by means of Langrangian multiplier method. (Author)
