ABSTRACT
Retrofitting interventions leading to uniform distribution of seismic forces are designed to improve the whole seismic performance. The existing bearings are replaced by elastomeric pads (Figure 2.a). To prevent jumping of the superstructure, longitudinal and transversal seismic restrainers are realized by means of reinforced concrete elements doweled to the existing cap beams (Figures 2.b-c). New expansion joints are also provided.
