Abstract :

Confined masonry construction is made up of masonry walls and confining ties, which are built on all four sides of each wall. This system is a conventional form for constructing houses as well as a good alternative for post-disaster reconstruction of the seismically damaged and/or collapsed buildings in many countries. Window and door openings appear in many panels of confined masonry buildings, but many codes do not consider the effect of these openings in the strength and the stiffness of confined masonry panels. In this study, the influence of area of openings on the stiffness and the strength of confined masonry walls is investigated. An experimental program is used to investigate the strength and stiffness of confined masonry walls; four specimens were used:-confined masonry wall without opening, confined masonry wall with opening of 20% wall area, confined masonry wall with opening of 25% wall area, and confined masonry wall with opening of 30% wall area. The results show that openings significantly reduce the lateral load resistant properties of the confined masonry.
