Abstract
Nonlinear analysis of RC deep beams strengthened with NSM CFRP anchor bars
Highlights
Rehabilitation and strengthening by using fiber reinforced polymer (FRP) as a near surface mounted (NSM) of members like beams and columns have become a good way to increase shear and flexural strength of existing composite members (Tavarez et al, 2003)
Many studies on strengthening and repairing by using NSM technique showed that using of FRP laminates to the reinforced concrete members provide efficiency, reliability and cost-effectiveness in rehabilitation
Using FRP as a NSM for strengthening and rehabilitation were proved to be successful in enhancing the shear capacity of reinforced concrete (RC) deep beams (Zhang et al, 2004; Islam et al, 2005; Maaddawy and Sherif, 2009)
Summary
Strengthening of composite members by externally bonded FRP laminates is very interested and accepted technique (Khalifa et al, 1998). Many studies on strengthening and repairing by using NSM technique showed that using of FRP laminates to the reinforced concrete members provide efficiency, reliability and cost-effectiveness in rehabilitation. Many studies were conducted to predict the shear and bending load capacity of FRP that used to strengthen and repair RC beams (Rahimi and Hutchinson, 2001; Al-Zaid et al, 2012; Camata et al, 2007; Yang et al, 2003; Supaviriyakit et al, 2004; Rabinovich and Frostig, 2000). Using FRP as a NSM for strengthening and rehabilitation were proved to be successful in enhancing the shear capacity of RC deep beams (Zhang et al, 2004; Islam et al, 2005; Maaddawy and Sherif, 2009).
