Seismic retrofitting of bridges
2008Retrofitting 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 ...

Retrofitting of a seismically deficient building
Journal of Structural Integrity and Maintenance, 2016AbstractMost available seismic retrofitting methods have certain degree of difficulty to be implemented on site and are thus more expensive. A relatively new retrofitting technique coupling the conventional braces with the recently developed viscoelastic dampers is proposed to improve the seismic performance of deficient structures in more effective ...

An innovative seismic retrofitting technique for “as-built” reinforced concrete (RC) bridge piers was proposed, by using ultra-high performance fiber reinforced concrete (UHPFRC) jackets. One “as-built” and two UHPFRC jacket-retrofitted rectangular cross-

In this paper an efficient first-order multi-objective optimization scheme is adopted for the design of linear viscous dampers for the seismic retrofitting of frame buildings. A retrofitting cost function serves as one objective while the expected losses

Research on the seismic retrofitting performance of RC frames using SC‐PBSPC BRBF substructures
Earthquake engineering & structural dynamics (Print), 2020A new type of external substructure to upgrade existing reinforced concrete frames (RCFs) is presented in this paper, namely, a self‐centering precast bolt‐connected steel‐plate reinforced concrete buckling‐restrained brace frame (SC‐PBSPC BRBF).

A strong earthquake (Mw = 7.1) hit Mexico City at 13:14 local time on September 19, 2017. The earthquake severely damaged more than 600 buildings and more than 1000 buildings were classified in different risk levels.
