Development and implementation of RABIT (Robotics Assisted Bridge Inspection Tool) in condition assessment concrete bridge decks is described. The system uses multiple nondestructive evaluation (NDE) technologies in characterization of three most common deterioration types: rebar corrosion, delamination, and concrete degradation. The system implements four NDE technologies: electrical resistivi...

The construction and inspection of reinforcement rebar currently rely entirely on manual work, which leads to problems such as high labor requirements costs. Rebar image detection using deep learning algorithms can be employed in quality intelligent construction; it check the number, spacing, diameter a site, guide robots complete tying. However, application relies large number datasets train m...

Introduction: Ferrocement is a low-cost material that can be utilized as replacement for expensive fiber-reinforced polymer (FRP), which generally used retrofitting structural and non-structural reinforced concrete members. The objective of this paper to investigate the effectiveness wire mesh in flexural members such beams. It also investigated capacity beams, are with partial or complete regu...

Nonlinear simulations for structures under disasters have been widely focused on in recent years. However, precise modeling for the nonlinear behavior of reinforced concrete (RC) shear walls, which are the major lateral-force-resistant structural member in high-rise buildings, still has not been successfully solved. In this paper, based on the principles of composite material mechanics, a multi...

this report presents a 3.5-year-old boy who was hospitalized for limping. medical history and physical exams were not suggestive for any definitive diagnosis. laboratory and radiographic exams did not support any specific diagnosis either. subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

The effect of strain levels on the corrosion resistance an enamel-coated steel rebar is experimentally investigated in this study. Enamel coating was applied surface a by using wet process. A gauge attached coated to record and plastic container mounted for electrochemical tests. stress-corrosion test set-up designed conduct tensile tests simultaneously. considered include 0 µε, 300 600 900 µε ...

conclusions the causes leading to fracture of the humerus during the act of a throw are discussed and the management strategies utilized. introduction five patients presented to the emergency department of a tertiary referral teaching hospital with atraumatic fractures of their humerus sustained during a recreational dodgeball tournament. case presentation the patients were young healthy indivi...
