Italian Journal of Geosciences (2021) 140 (3): 365–381.
...Gaetano Falcone; Vitantonio Vacca; Federico Mori; Giuseppe Naso; Daniele Spina ABSTRACT Evaluation of seismic retrofitting costs, a key issue in the risk mitigation strategies, requires the estimation of the building performance and the forecast of the site response. In addition, a target building...

... after the seismic event. The aim of this study is to evaluate the effects of BRSs on seismic risk estimates and consequently on structural retrofitting cost-effectiveness. A loss model (including direct and indirect costs and BRS effects) was defined, based on a real-life case study (a biomedical...

... history analysis, considerably reducing computational demand. In this paper, a general methodology for performance-based retrofitting of typical steel frames by the ET method is discussed. A baseline steel moment-resisting frame is considered, and its seismic performance is evaluated by the ET method...

... dissipation capacity of thin-walled, R/C shaft supports. Concrete jacketing is used as a retrofit measure to enhance the lateral strength and ductility by changing the failure mode of concrete crushing to a more ductile tension yielding. This scheme requires substantial strengthening of the existing...

Earthquake Spectra (1997) 13 (2): 281–304.
... utilizing fiber reinforced polymer (FRP) composites to retrofit existing bridge columns is investigated in this paper. High-strength FRP straps are wrapped around the column in the potential plastic hinge region to increase confinement and to improve the behavior under seismic forces. Five rectangular...

Earthquake Spectra (1997) 13 (2): 225–241.
...Mohammad R. Ehsani, M.EERI; Hamid Saadatmanesh A new approach for seismic retrofitting of lightly-reinforced precast-concrete walls is presented. The technique involves epoxy bonding the reinforcing material (composite fabric) to the exterior surface of the wall. The flexible light-weight fabrics...

...J. Aguilar; H. Juárez; R. Ortega; J. Iglesias The 1985 Mexico City earthquake caused very serious damage, especially in reinforced concrete buildings, making it necessary to repair and strengthen many structures. The authors had the opportunity to study 114 of these retrofitted buildings. The data...
