Resumen:

A solution is presented to reduce the transverse displacements of an urban cable-stayed bridge using viscoelastic energy dissipating devices. A displacement-based dynamic modal method is proposed oriented to design the dampers. The algorithm uses an equivalent single-degree-of-freedom system and uniform hazard pseudo-displacement response spectra. The design method is applied in an illustrative example.
