Modelling the ASCE Cable-Stayed Bridge Benchmark with Passive Devices.

The ASCE benchmark cable-stayed bridge has gathered, in the last years, the interest of many specialists in the field of the structural control and the dynamic response of long span bridges. Starting from the structural model of the original benchmark statement, a refined version is developed in a commercial finite element environment so as to include new modelling aspects: (1) in the simulation of the stay cables dynamics, with respect to the coupled motion with the main girder, and (2) in the implementation of the seismic external excitation. Finally, some passive control strategies for the mitigation of the seismic effects on the bridge response are implemented.
