Performance and Seismic Vulnerability of Masonry Housing Types Used in Chile
Publication: Journal of Performance of Constructed Facilities
Volume 18, Issue 3
Abstract
Masonry is the most used construction material, especially for residential dwellings built in all regions of Chile, up to four stories high. The masonry wall’s reinforcement of these buildings can be classified into three types: confined, reinforced and hybrid. Although buildings with confined masonry walls have limited shear strength and ductility, they have demonstrated acceptable seismic behavior. Experience for buildings with the other two types of reinforcement has been different; during the 1985 Llolleo earthquake several buildings had severe damage due to design and construction deficiencies. In this paper a description of key structural features, construction process, seismic resilient features and deficiencies of masonry housing types used in government-subsidized low-income dwellings is provided. In addition, various seismic vulnerability indices that characterize their seismic behavior are calculated. The evolution over time of such indices shows that nowadays a large amount of buildings are likely to be damaged after a severe earthquake.
