As we all know that there was severe damage of beam-to-column connections especially in the regions with high seismicity, such as Northridge of the United States, Hanshin of Japan and Wenchuan of China (Popov et al in Eng Struct 20(12):1030–1038 1998; Miller in Eng Struct 20(4–6):249–260, 1998).

Retrofitting of RC Beams: A Review
Applied Mechanics and Materials, 2016Reinforced concrete (RC) is the most popular building material in the construction industry. It is a composite material in which low tensile strength and ductility of concrete are counteracted by the inclusion of reinforcement having higher tensile strength and ductility.

AbstractThe ability of a RC beam to rotate is extremely important at both the serviceability and ultimate limit states as it affects deflection, moment redistribution, and the absorption of energy. The rotation in a RC beam can be considered to have two components: the continuous rotation that occurs in the homogenous portions of the beam and that can ...

Experimental study of RC jacketed and CFRP strengthened RC beams
Construction and Building Materials, 2015Abstract This paper presents the results of an experimental study on retrofitting RC beams using FRP strengthening and RC jacketing. Three-point loadings are applied to twelve strengthened beams and three reference specimens to put the two techniques into perspective.

Numerical Analysis of RC Beams Strengthened with SRG
SP-324: Composites with Inorganic Matrix for Repair of Concrete and Masonry Structures, 2018The use of Fiber Reinforced Polymer (FRP) strengthening systems for reinforced concrete (RC) members represents nowadays an effective alternative to traditional strengthening techniques. Recently, a new class of composites have emerged known as Steel Reinforced Grout (SRG), consisting of steel fibers embedded in an inorganic matrix and applied by using

Anchorage of composite laminates in RC flexural beams
Structural Concrete, 2010This paper focuses primarily on flexural strengthening with pre-cured fibre-reinforced polymer laminates applied on reinforced-concrete beams with different anchoring devices, both chemically and mechanically applied. The results showed that the ultimate load of the strengthened beams was 35–80% higher than the control beam, depending on the type of ...

Interrelation of Splitting and Flexural Cracks in RC Beams
Journal of Structural Engineering, 1998The durability of reinforced concrete (RC) structures depends mainly on concrete permeability that allows the aggressive agents to reach the reinforcement and to start corrosion. In addition to the permeability connected to porosity and microcracking, another important and well-known cause of degradation is concrete cracking that directly exposes the ...
