Seismic response of a cable-stayed bridge: Active and passive control systems (benchmark problem)

This paper describes the Benchmark Problem for controlled cable-stayed bridges. The benchmark in question is the first to be related directly to bridges. It follows on from past experience and experimentation, devoted to buildings, developed at an international level. These past experiences focused upon buildings subjected to wind and earthquake excitation. In this paper seismic excitation is explored in relation to bridges. Three different schemes of active control are compared with each other. Their performance is also compared with the two most widely used passive control systems which summarize present energy dissipation practice. Copyright © 2003 John Wiley & Sons, Ltd.
