A Beam Finite Element for Shear-Critical RC Beams

SP-237: Finite Element Analysis of Reinforced Concrete Structures, 2006
The proposed beam finite element is capable of describing the response of reinforced concrete members under the interaction of axial force, shear, and bending moment. The element is based on a mixed formulation and does not exhibit the shear locking problems of displacement-based elements.

Required plastic rotation of RC beams

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2006
Linear analysis with moment redistribution has been allowed under codes of concrete structures for a long time. There is, however, still a certain lack of consensus regarding the value of the redistribution coefficients. The calculation of those coefficients ignores the influence of some factors in moment redistribution, and this may lead to designs ...

Postcracking Compliance Analysis of RC Beams

Journal of the Structural Division, 1979
An analytical model for postcracking compliance of rectangular reinforced concrete beams under combined torsion, bending, and transverse shear is established using the skew bending theory. The case of small transverse shear and the case of large transverse shear are treated separately based on widely accepted failure modes.

Behaviour of strengthened RC T-beams

Magazine of Concrete Research, 1995
Twelve reinforced concrete T-beams were each strengthened in shear by the incorporation of additional stirrups in a thickened section cast using non-shrink grout. Another beam was strengthened by thickening the existing section only, without any additional reinforcement.

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 ...

Beam Commissioning Experience of CSNS/RCS

2019
The China Spallation Neutron Source (CSNS) is an accelerator-based science facility. CSNS is designed to accelerate proton beam pulses to 1.6 GeV kinetic energy, striking a solid metal target to produce spallation neutrons. CSNS has two major accelerator systems, a linear accelerator (80 MeV Linac) and a 1.6 GeV rapid cycling synchrotron (RCS).

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

Minimum Reinforcement Requirement for RC Beams

1999
ABSTRACT In the present paper different aspects of the requirement for the minimum reinforcement ratio are studied and discussed. The influence of the beam depth is investigated in more.detail. Numerical analysis for reinforced concrete beams of different sizes is carried out using plane finite element code MASA2 which is based on the nonlocal ...

Nonlinear FE Analysis of RC Beams

2001
ABSTRACT A moment-curvature relationship to simulate the behavior of reinforced concrete beam under cyclic loading is introduced. Unlike previous moment-curvature models and the layered section approach, the proposed model takes into consideration the bond-slip effect by using monotonic moment-curvature relationship constructed on the basis of the ...

Impact Loading on RC Cantilever Beam

Proceedings of the Bulgarian Academy of Sciences
Structural elements are designed to resist several static and dynamic load combinations. On the other hand, impact loading is not considered in the design of these elements. However, failure modes may occur under sudden impact effects. In this study, it is aimed to investigate the impact behaviour of a reinforced concrete cantilever beam.
