Experimental investigation and numerical analysis of RC beams shear strengthened with FRP/ECC composite layer

, 2020
Five Reinforced Concrete (RC) beams strengthened with Basalt Fiber Reinforced Polymer (BFRP) grid in conjunction with Engineered Cementitious Composite (ECC) were tested along with one conventional RC beam for reference to investigate their performance ...

Discrete Rotation in RC Beams

Journal of Engineering Mechanics, 2012
AbstractThe ability of a RC beam to rotate is extremely important at both the serviceability and ultimate limit states as it affects deflection, moment redistribution, and the absorption of energy. The rotation in a RC beam can be considered to have two components: the continuous rotation that occurs in the homogenous portions of the beam and that can ...

Beam collimation for CSNS/RCS

Chinese Physics C, 2010
The current design of the CSNS/RCS beam collimation system consists of a two-stage betatron collimation and a single momentum collimator. This paper summarizes various aspects of collimator design, including collimation principle and layout, material choice and collimator mechanical structure, etc.

Flexural behavior of RC beams strengthened with BFRP bars-reinforced ECC matrix

Composite structures, 2020
This paper has proposed a new strengthening system made of basalt fiber-reinforced polymer (BFRP) bars-reinforced engineered cementitious composite (ECC) matrix (hereinafter referred to as “BFREM” for brevity) for repairing of RC beams.

Experimental study of RC jacketed and CFRP strengthened RC beams

Construction and Building Materials, 2015
Abstract This paper presents the results of an experimental study on retrofitting RC beams using FRP strengthening and RC jacketing. Three-point loadings are applied to twelve strengthened beams and three reference specimens to put the two techniques into perspective.

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.

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.

Influence of drop weight geometry and interlayer on impact behavior of RC beams

International Journal of Impact Engineering, 2019
A number of drop weight tests on reinforced concrete (RC) beams have been reported in literature. These tests conducted by different researchers used drop weight of different geometries.

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.

Performance of externally strengthened RC beams with side-bonded CFRP sheets

Composite structures, 2019
The conventional method of strengthening reinforced concrete (RC) beams in flexure is via bonding carbon-fiber reinforcement polymer (CFRP) laminates to the beam’s soffit. However, the beam’s soffit could be narrow or inaccessible for strengthening.
