12  Under earthquake quake shaking, the masonry acts as compressive diagonal struts and the RCC confining element act as tension and compression member.  The RCC element grip the whole width of the wall at the door and window opening and prevent damage of wall.

13  Low rise ( one to two) storey confined masonry Building have performing very well in Latin America in recent earthquakes.  Confined masonry performed well in EL Salvador Earthquake of January 13 and February 13,2001 (Magnitude 7.7 and 6.6). 90% of the building constructed with confined masonry did not collapse.

14  Performance of confined masonry building in August 2007, Pisco Peru Earthquake.  a). Six story confined masonry building remained undamaged.  b). Collapse of a confined masonry building due to soft story effect
