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.

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.
