A new reinforced concrete beam [PDF]

WIT Transactions on The Built Environment, 2012
The introduction of high strength concrete and steel reduces the size of structural members whilst having the same load carrying capacity and a resultant saving on construction time, material, labour and space. Therefore, using both high strength steel and high strength concrete in construction is very important for producing a lightweight structure ...

Toward Mechanical Intelligence in Robotics

Advanced Robotics Research, EarlyView.
Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.

Rehabilitation of Reinforced Concrete Beams

Tikrit Journal of Engineering Sciences, 2017
The concrete structures are often exposed to damage as a result of several factors including, environment, design, and other factors, and because of the high cost and long time needed for reconstruction of the damaged buildings, it become necessary to consider methods for rehabilitation of the damaged structural member in the building.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Behavior of reinforced concrete beams reinforced with GFRP bars

Revista IBRACON de Estruturas e Materiais
The use of fiber reinforced polymer (FRP) bars is one of the alternatives presented in recent studies to prevent the drawbacks related to the steel reinforcement in specific reinforced concrete members.

Cracking behaviour and its effect on the deflection of patched-reinforced concrete beam under flexural loading

MATEC Web of Conferences, 2017
Under the influence of aggressive environment, structural concrete could exhibit degradation in various forms. One of the symptoms of the degradation could be shown in the form of local delamination of concrete cover.

Nanoscale Secondary Ion Mass Spectrometry for Quantifying Membrane Fouling: Fouling Layer Structure and Chemical Interaction

Advanced Science, EarlyView.
Nanoscale secondary ion mass spectrometry (Nano SIMS) is established as a powerful analytical tool to visualize and quantify the membrane fouling layers. ABSTRACT Membrane technology has garnered considerable attention for applications in wastewater treatment and resource recovery. Nevertheless, membrane fouling remains a major barrier, yet the lack of

Test and prediction of shear strength for the steel fiber–reinforced concrete beams

Advances in Mechanical Engineering, 2019
The ultimate load capacities of steel fiber–reinforced concrete beams were determined by experiments conducted on steel fiber–reinforced concrete beams under the action of a two-point symmetrical concentrated load.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
