Título del libro: 8th Us National Conference On Earthquake Engineering 2006 Título del capítulo: Improving the earthquake resistance and sustainability of confined masonry (MIXTO) dwellings in EL salvador
The seismic vulnerability of housing stock in El Salvador was demonstrated during the recent 2001 earthquakes. Relative to other types of common residential construction, mixto dwellings (a form of confined masonry) performed well. A coordinated pilot study was conducted with the objective of improving the seismic resistance of this form of construction while reducing costs and greenhouse gas emissions. Laboratory tests examined brick strength in relation to firing temperature and duration. Analytical studies examined the potential for voided bricks to improve seismic performance and the reduction in demands associated with stiffening the roof diaphragm. This pilot study identifies the potential for reduced construction costs, reduced greenhouse gas emissions, and significant performance enhancements.
