Feasibility Study on the Effect of FRP Shear Reinforcements on the Behaviour of FRP-Reinforced Concrete Deep Beams

open access: yesCivilEng, 2023
Unlike steel reinforcements in concrete, Fiber Reinforced Polymer (FRP) materials are light and free from corrosion. Therefore, FRP materials are increasingly being used in structural engineering as a replacement for steel reinforcements.

Numerical simulation of the mechanical performance of deep beam

open access: yesRevista IBRACON de Estruturas e Materiais
The purpose of this paper is the analysis of the mechanical performance of concrete deep beams. To overcome the shortcomings inherent to the pioneer models, the finite element approximation on a non linear orthotropic model is employed.

Simulations of deep pencil-beam redshift surveys [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2001
We create mock pencil-beam redshift surveys from very large cosmological $N$-body simulations of two Cold Dark Matter cosmogonies, an Einstein-de Sitter model ($ $CDM) and a flat model with $ _0 =0.3$ and a cosmological constant ($ $CDM). We use these to assess the significance of the apparent periodicity discovered by Broadhurst et al.

Strengthening Solutions for Deep Reinforced Concrete Beam with Cutout Opening

open access: yesBuildings, 2021
Since reinforced concrete (RC) buildings have long service life, cutout openings are generally needed in their load-bearing walls as a sustainable solution in order to meet new requirements of their users.

Influence of Multiple Openings on Reinforced Concrete Outrigger Walls in a Tall Building

open access: yesApplied Sciences, 2019
Outrigger systems have been used to control the lateral displacement of tall buildings. Reinforced concrete (R.C.) outrigger walls with openings can be used to replace conventional steel outrigger trusses.

Finite element investigation of the shear performance of corroded RC deep beams without shear reinforcement

open access: yesCase Studies in Construction Materials, 2021
The shear behavior of reinforced concrete (RC) beams has been the principal subject of research studies. However, the structural behavior of RC deep beam without shear reinforcement is still complex and not well-understood.

Modification of strut effectiveness factor for reinforced concrete deep beams strengthened with CFRP laminates

open access: yesMateriales de Construccion, 2014
This paper proposes a method to modify the strut effectiveness factor in the strut-and-tie model for CFRP-strengthened reinforced concrete deep beams.

Development of strut and tie models for simply supported deep beams using topology optimization [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2008
Generally, structural members can be broadly divided into two regions, namely B, or Bernoulli regions, where the strain distributions are linear and D, or Disturbed regions, where the strain distributions are nonlinear While well defined theories are ...

Crack propagation modeling of strengthening reinforced concrete deep beams with CFRP plates

open access: yesMaterials Research Express, 2021
Fracture analysis of reinforced concrete deep beam strengthened with carbon fiber-reinforced polymer (CFRP) plates was carried out. The present research aimed to discover whether crack propagation in a strengthened deep beam follows linear elastic ...

Behaviour of unstrengthened and DE CFRP-strengthened high-strength concrete deep beams with web openings

open access: yesFrontiers in Materials
The existing web opening created in shear span of concrete deep beams due to reasons such as accommodating utility pipes or cables resulting in a reduction in a load bearing capacity.
