Passive and Semi-Active Seismic Protection of the ASCE Cable-Stayed Bridge

The interest of many specialists in the field of structural control and dynamic response of long span bridges was attracted in the last years on the ASCE benchmark on cable-stayed bridges. Starting from the structural model of the benchmark original statement, a refined version is developed in a commercial finite element environment (Ansys) so as to include new aspects: - in the simulation of the stay cables dynamics, with respect to the coupled motion with the main girder; - in the implementation of the seismic excitation. Finally, the Bouc-Wen model is implemented for a better simulation of the control devices.
