Experimental evaluation of out-of-plane strength of masonry walls retrofitted with oriented strand board

Structural retrofitting is carried out as an economical alternative to demolishing and rebuilding existing masonry structures. Retrofitting provided offer structural upgrade damage-control. This paper presents the application of oriented strand board type 3 (OSB/3) for unreinforced walls. Out-of-plane bending test in form four-point loading was performed on six The results show that OSB/3 can considerably increase load flexure capacity by (1.4 & 1.8), limiting-toughness (1.6 2.4) overall-toughness (16 10) times compared plain wall subjected out-of-plane (single double-sided) respectively.
