structural steels with very high strength levels are often referred to as ultrahigh-strength steels (uhss). the usage of uhss has been extensively studied in aerospace industries and offshore platforms. in this study, medium carbon low alloy steel (ams6305) was thermomechanicaly treated to obtain an ultra-high strength bainitic steel for aircraft engine compressor disk. a novel themomechanical ...

Concrete cover cracking induced by reinforcement corrosion is an important indication of the durability limit state for reinforced concrete (RC) structures and can be used to determine structural service life. The process rebar from beginning rusting occurrence due expansion divided into two phases: phase free product cracking. Based on assumption uniform reinforcement, one model predicting dep...

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...

Due to the assumption of uniform bond stress, development length fibre reinforced polymer (FRP) bars by design standards can be unnecessarily long and difficult provide in practice. Hence, stress distribution required a glass (GFRP) rebar is investigated. Four beam-bond specimens, two following RILEM specifications based on procedure ACI are tested evaluate effect test method strength. Ten pull...

Adequate rebar-concrete bonding is crucial to ensure the reliable performance of reinforced concrete (RC) structures. Many factors such as properties, cover depth, transverse reinforcement, and presence corrosion will affect bond behavior, consequently, structural performance. While many prior studies have focused on influence aforementioned strength, impact these failure mode has not been thor...

A 42-year-old woman was referred to our institution with sudden onset of ataxia, facial paresis, horizontal gaze palsy, and progressive dysarthria. The patient worsened within a few minutes, with appearance of left hemiparesis. The National Institutes of Health Stroke Scale Score was 13. On computer tomography scan 2 hours after stroke onset, no brain stem lesion or intracranial bleeding was vi...
