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 ...

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.

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.

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.

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.

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 ...

Reliability of RC Beams Subjected to Fire

Journal of the Structural Division, 1977
Methods for analytically predicting the behavior of reinforced concrete beams subjected to fire are presented. These incorporate the temperature-dependent strength degradation in the steel as well as thermal and creep strains. The parameters that are important for predicting beam behavior are identified through a sensitivity study.

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.

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.

Modeling of creep in GFRP RC beams

2013 5th International Conference on Modeling, Simulation and Applied Optimization (ICMSAO), 2013
The laws of creep following the Eurocode 2 recommendations are investigated. Analytical study was also conducted including creep under constant stress; successions of increasing stress superposition principle equivalent time and the return creep reloading.
