The Development Length and Anchorage Behavior of Headed Reinforcing Bars
Research has been conducted by several investigators on a new, innovative type of reinforcement, referred to as the headed bar. The development of the headed bar resulted out of the need to reduce the development length of the bar and anchor the reinforcement in a shorter length. Construction in earthquake prone regions and designing for blast or impact conditions requires dense reinforcement c...
متن کاملNumerical investigation of GFRP bars contribution on performance of concrete structural elements
In this study, twenty glass fiber reinforced polymer (GFRP) reinforced concrete specimens were modelled using finite element method to predict the effect of GFRP compressive bars on the flexural strength and ductility of GFRP reinforced concrete beams. Also, the contribution of GFRP longitudinal rebars to the load-carrying capacity of reinforced concrete columns is determined. The concrete elas...

متن کاملNumerical Study on the Flexural Behaviour of Concrete Beams Reinforced by GFRP Bars
Enhancement of the response of reinforced concrete (RC) beams using fiber-reinforced polymer (FRP) reinforcement bars has become a popular structural technique over the past two decades due to the well-known advantages of FRP composites including their high strength-to-weight ratio and excellent corrosion resistance. Thisstudy presents n...
متن کاملOut-of-plane Behavior of Urm Walls Strengthened with Nsm Gfrp Bars
Unreinforced masonry (URM) walls are prone to failure when subjected to out-of-plane loads caused by earthquakes or high wind pressures. In this context, fiber reinforced polymer (FRP) materials may be a solution to solve or lessen the effects of this overloading. This paper describes an experimental program dealing with the flexural behavior of nine concrete URM walls strengthened with glass F...
