Discrete Rotation in RC Beams

Journal of Engineering Mechanics, 2012
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 ...

The Probabilistic Calculation Model of RC Beams, Strengthened by RC Jacket

2020
According to the engineering method of calculation of normal cross section of reinforce concrete beam with use of the basic concepts of probability theory and random function theory, is proposed the probabilistic calculation model of rectangular reinforce concrete beams, strengthened by reinforce concrete jacket under loading. Real-operating conditions

Experimental study of RC jacketed and CFRP strengthened RC beams

Construction and Building Materials, 2015
Abstract 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.

Anchorage of composite laminates in RC flexural beams

Structural Concrete, 2010
This 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 ...

Numerical Analysis of RC Beams Strengthened with SRG

SP-324: Composites with Inorganic Matrix for Repair of Concrete and Masonry Structures, 2018
The 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

Interrelation of Splitting and Flexural Cracks in RC Beams

Journal of Structural Engineering, 1998
The 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 ...

Analytical analysis of interfacial stresses in FRP-RC hybrid beams with time-dependent deformations of RC beam

Acta Mechanica Solida Sinica, 2011
In this paper, the effect of time-dependent deformations (such as shrinkage and creep) on the interfacial stresses between an RC beam and FRP plate is presented. For this end, a closed-form solution for such stresses in externally FRP plated RC beams including creep and shrinkage effects is presented.

Tests on RC Continuous Beams with Openings

Journal of Structural Engineering, 1991
An experimental investigation is carried out on eight reinforced‐concrete continuous beams, each containing a large transverse opening. The beams are rectangular in cross section and all contain the same amount and arrangement of longitudinal reinforcement.

Shear strength of plated RC beams

Magazine of Concrete Research, 1995
Use of externally bonded plates to strengthen or repair damaged reinforced concrete (RC) beams and slabs has gained universal acceptance. However, questions remain regarding the possibility of a highly brittle mode of failure, referred to in the literature as shear failure for certain combinations of plate geometry and other parameters.

RC beam with variable stiffness and strength

Construction and Building Materials, 2006
Abstract Shape memory alloys (SMA) show a temperature depending stiffness and strength. A reinforced concrete (RC) beam with SMA wires was tested and compared with a conventional RC beam. Furthermore, tensile and pull-out tests with the SMA wires are presented.
