Appraising the Seismic Response of a Retrofitted Adobe Historic Structure, the Role of Modal Updating and Advanced Computations

The concepts of structural assessment and retrofit historical constructions are particular complexity require advanced knowledge in material science, conservation techniques analysis. In particular, adobe constructions, given their low mechanical properties brittle failure modes, immense need comprehensive retrofitting plans. current work focuses on the Church Kuñotambo Peru, having experienced long periods deterioration earthquake-related damage. Under ongoing Seismic Retrofitting Project (SRP) Getty Conservation Institute (GCI), church initiated 2015 confirmed lateral capacity building poor connectivity between parts. Based existing cracks damage, a strengthening scheme was optimized validated. After implementation plan, quality its execution efficiency were assessed 2019 with new situ campaign, which included ambient vibration testing (AVT) sonic testing. From acquired field data, FE model retrofitted optimized, by updating stiffness masonry discontinuities. Moreover, nonlinear static analyses performed updated all in-plan directions. Finally, displacement-based performance undertaken, under different earthquake limit states, demonstrating adequacy retrofitting.
