ABSTRACT

This chapter provides the results of in situ testing and modelling of four case studies in Peru and is part of the ongoing Seismic Retrofitting Project, under the auspices of the Getty Conservation Institute: Casa Arones, Hotel Comercio, Ica Cathedral and Kuno Tambo. It addresses the seismic vulnerability of two of the four case studies using advanced numerical simulations and pushover analyses. The objective of the dynamic identification tests was to determine the natural frequencies, the mode shapes and the damping ratios of the structures. The overall behavior of the buildings has been characterized by performing identification tests in order to try to provide their dynamic characteristics using the ambient vibration as a source of excitation. The dynamic identification tests allowed to characterize the elastic behavior of the real structure, allowing defining also global Young’s Modulus of the structures and validating the quality of the connections between different structural elements.
