Retrofitting of RC Beams: A Review

Applied Mechanics and Materials, 2016
Reinforced 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.

Progressive collapse resistance of RC beams

Engineering Structures, 2015
Abstract The current guidelines for evaluating progressive collapse potential of existing and new buildings require analyzing and evaluating the structure for the case of an instantaneous loss of a primary vertical support, such as a column. In this paper, the response of a continuous beam bridging over a lost column is evaluated.

Long‐Term Deflection of RC Beams

Journal of Structural Engineering, 1994
Long‐term deflection of statically determinate reinforced concrete beams under service loads is analytically studied. The BP‐2 creep and shrinkage model is adopted and extended to accommodate concrete tensile behavior by assuming a tensile stress‐strain relation.

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.

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).
