✦ Synopsis

In this paper, a new disturbance rejection controller is used to improve the response of a bridge during the application of environmental excitations. The controller combines global linearization of a non-linear bridge model and robust controller design to achieve its objectives. The resulting controller is robust with respect to disturbances, modelling errors and controller implementation errors. The method is applied to the Aptos Creek bridge in Santa Cruz under excitation caused by El-Centro earthquake.

Seismic response of a one-storey structure with sliding support to bidirectional (i.e. two horizontal components) earthquake ground motion is investigated. Frictional forces, which are mobilized at the sliding support, are assumed to have ideal Coulomb-friction characteristics. Coupling effects due
