Strengthening of RC beams with ferrocement laminates

Cement and Concrete Composites, 1998
Abstract In this paper methods of repair and strengthening of reinforced concrete beams using ferrocement laminates attached onto the surface of the beams are reviewed. Investigation into the transfer of forces across the concrete/ferrocement interface, the effects of the level of damage sustained by the original beams prior to repair, and the ...

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.

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.

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.

Ductility of RC beams under torsion

Engineering Structures, 2018
Abstract In this article, the torsional ductility of reinforced concrete (RC) beams with rectangular cross section is studied. For this, the experimental results of several RC beams found in the literature were compiled and analyzed. A torsional ductility index was used to characterize the torsional ductility of the studied beams.

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 ...

Crack Resistance of RC Beams on the Shear

2019
Most important parameter of serviceability limit state (SLS) for reinforced concrete (RC) beams is crack resistance. These include width of crack opening, cracking distribution, load at which is achieved limit and maximum width of crack opening. This is especially important for shear resistance.

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 ...

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).

Deflection and ductility of continuous RC beams

Magazine of Concrete Research, 1993
Recent research work by the Author in the fields of deflection and ductility of reinforced concrete beams has shown that in design-oriented procedures both these aspects can be controlled through effective depth-linked requirements. The present study compares the required effective depth to meet a specified deflection limit with the effective depth ...
