Prestressed CFRP Plates and Tendon Strengthening of Steel–Concrete Composite Beams

Journal of Composites Science
This study aims to enhance the ultimate capacity and stiffness of steel–concrete composite beams through external strengthening with prestressed carbon fiber-reinforced polymer (CFRP) plates and post-tensioned CFRP tendons.

Behavior of Beams Strengthened with Steel Fiber RC Overlays

Journal of Advanced Concrete Technology, 2009
Strengthening of reinforced concrete beams using steel fiber reinforced concrete (SFRC) overlays has been investigated in the test program described in this paper. Two methods have been used to connect the overlays to the original beams, i.e. chemical and mechanical bonding.

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Flexural behavior of steel fiber reinforced concrete beams comprising coarse and fine rubber and strengthened by CFRP sheets

Heritage and Sustainable Development, 2023
Despite having many advantages, using rubber to produce reinforced concrete members like beams is still restricted. When there is more waste tire rubber in concrete structures, rubber concrete's flexural and compressive strengths gradually decrease ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Embedded Connector in Severe Optimization of Steel Plate for Shear Strengthening of RC Beam: Experimental and Numerical Investigations

Advances in Civil Engineering, 2018
Environmental impact has become one of the major factors taken into consideration for recent civil engineering studies and projects. Thus, researchers have been concentrating on shear strengthening of existing reinforced concrete structure as an upgrade ...

Investigation of Steel I-Beams Strengthened Using CFRP and BFRP Sheets under Torsion

Advances in Civil Engineering, 2023
Torsional demand acting on beams can significantly effect structural behavior and cause high-local stresses. The torsional resistance of beams can be potentially increased by using fiber-reinforced polymer (FRP) sheets.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Investigation and numerical analysis of steel beams strengthened with CFRP

Revista Internacional de Métodos Numéricos para Cálculos y Diseño en Ingeniería, 2021
One of the most common methods of strengthening concrete structures is the use of composite fibers such as FRP. These fibers have found a special place in structural retrofitting methods due to a number of specific ability including lightness and ease of performance.
