Seismic Assessment and Structural Retrofitting of the Church of San Pedro De Atacama, Chile


Abstract eng:
The vulnerability of earthen buildings in seismic areas may require special attention to avoid injury or loss of life and to also make a future seismic retrofitting possible. The considered reinforcements must comply with fundamental concerns of heritage conservation, as well as minimum intervention for authenticity, compatibility with the original materials to avoid damages, and reversibility to allow applying better solutions appearing in the future. This paper presents a case study of a seismic retrofitting project of the historical adobe church of San Pedro de Atacama in Chile. A parametric modal analysis was carried out to identify and analyze vulnerable areas, and to understand the dynamic behavior and the necessity of strengthening to control displacements in the walls and the main structural elements. The paper describes finally in detail the retrofitting process carried out in the church which convert it as one of the few cases in the world where an actual seismic retrofitting solution compatible to earthen buildings and seismic prone regions was implemented.
