Abstract

A suspended bridge model is developed at numerical level, its global geometry is freely inspired by the Shimotsui-Seto Bridge in Japan. A commercial finite element code is used to simulate the structural response under the wind buffeting excitations and structural control solutions are also modelled to evaluate their efficiency in the mitigation of unwanted dynamic effects. Passive control strategies have been implemented herein for the protection of the suspended bridge. Different typologies of passive devices are applied on the bridge model between the deck and the towers in different connection schemes. The control devices are defined as smart systems combining together different features (as rigid thresholds, springs, dampers, hysteretic tools, gaps). The bridge response for each controlled solution is compared to the uncontrolled one for demonstration and validation of the mitigation strategies. © 2007 Civil-Comp Press.
