Abstract

The architectural heritage conservation, built with traditional adobes masonry techniques, presents significant difficulties where these buildings are located in seismic context such as Chile. This article describes the criteria and intervention techniques that are designed for recovery earthquake resistant a religious set of colonial type that has been damaged with significant cracks and unaligned after the earthquake of 2010 and should be restored because it is a National Monuments. These interventions are designed taking into account the seismic behavior of the whole, which has been determined by the assessments made in the diagnostic pre and post-earthquake. These assessments demonstrate empirically the different resistance capacity of the building, varying in relation to their conservation and the existence of some reinforcement elements. Interventions seek to recover those elements that have had a good performance against seismic thrusts and otherwise reinforcing the existing structure that has had less damage, mainly with wooden exoskeletons and geogrids, looking compatibilities between building systems. More radically it has been rebuilt a pavilion, with the difficulty of complying a seismic regulations in a work that, for its historical value, must preserve the shape and traditional construction systems. This project is an example of the intervention techniques that are being made in Chile taking into account the considerations of the new regulations for reinforcement and repairs of heritage structures in adobe.
