There is an ongoing initiative to use confined masonry in Algeria, but the application has been limited. First applications are reported in M’sila where a few houses were built using this technology. In 2008-2010 a confined masonry housing program was implemented in the Wilaya of Médéa (about 100 km south-west of Algiers). Confined masonry buildings in Algeria are built using stone masonry. Stone is a locally available material and has been traditionally used for masonry construction in the country. Confined masonry has been addressed by the Algerian seismic code starting in 2003 (RPA 99/version2003).
Confined masonry buildings were exposed to the 2010 Msila earthquake in Algeria (magnitude 5.2) and remained undamaged, while unreinforced masonry and reinforced concrete frame construction experienced damage in the earthquake.
