The use of fiber reinforced polymer for strength and strain enhancements of concrete columns
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 10
Abstract
When a masonry wall acts as a slab for example due to wind or earthquake loads perpendicular to the plane of the wall, tensile stresses caused by moments and shear stresses occur. The popularity of higher strength concretes in the construction industry has been on a steady incline during the last two decades because of the superior performance and economy offered by high-strength concrete (HSC) over normal-strength concrete (NSC) in a large number of structural engineering applications. An alternative method for strengthening and retrofitting masonry structures is the use of fibre reinforced polymer (FRP) composites, adhered to the surface of the wall to resist lateral loads. The use of FRP composites has emerged as a promising retrofit solution and grown very rapidly in recent years. FRP materials show high strength to weight ratio, resistance to chemical and environmental corrosion, fatigue resistance and formability to complex shapes. They are quick to apply and the cost of these materials has dropped significantly in recent years.
