Seismic design and retrofit of bridges
Bulletin of the New Zealand Society for Earthquake Engineering, 2000 The 1989 Loma Prieta, 1994 Northridge and 1995 Hyogo-ken nanbu earthquakes caused major damage to bridges and these events together with the research triggered as a consequence of the earthquakes has led to significant advances in bridge seismic design and retrofitting.

Seismic Evaluation and Retrofit of Historical Churches
Structural Engineering International, 2002 A methodology for evaluating the seismic response capacities of historical churches is presented. Specially calibrated performance objectives, including the issue of cultural value safety, and related acceptance criteria are formulated to this aim. A mixed displacement and strength-based control of response is carried out, by interpreting the results ...

Geotechnical aspects on seismic retrofit [PDF]
Procedia Structural Integrity, 2018 Abstract In the paper numerical analysis of foundation of damaged masonry structure using finite element method is presented. Retrofitting of those structures has been performed using technology DC90. By retrofit design, the foundation structure is confined with the foundation collar, connected by anchors and in which the vertical stiffening elements
