Computers and Structures Volume 170, 1 July 2016, Pages 13-25 An optimization model for the design of network arch bridges (Article) Bruno, D. , Lonetti, P. , Pascuzzo, A. Department of Civil Engineering, University of Calabria, Cubo39-B, Via P. Bucci, Rende, Cosenza, Italy View references (26) Abstract A new design methodology, which evaluates the optimum configuration of network arch bridge schemes is proposed. A three-step optimization algorithm is implemented in a FE model, with the purpose to evaluate the bridge optimum configuration, involving the lowest material quantity and the best strength performance level in all structural members of the bridge. The stability and the efficiency of the formulation were verified with respect to several bridge configurations ranging from small to large spans. Moreover, parametric results are presented to investigate the interaction between cable-system, girder and arch, giving rise to specific analyses useful for design purposes.
