This paper deals with an experimental study on the tensile performance of recently developed “FRP Hybrid Bars” by authors. The objective of this study is to investigate tensile strength of FRP Hybrid Bars and to overcome the shortcomings of the FRP material with its low elastic modulus. This uses the concept of material hybridization to increase elastic modulus to be used in concrete structures...

Lifting and carrying heavy loads occur frequently among ironworkers and result in high prevalence and incidence rates of low back complaints, injuries and work-disability. From a health perspective, little information is available on the effect of team lifting on work demands and workload. Therefore, the objective of this study was to compare the effects of team lifting of maximally 50 kg by tw...

Infrastructure health monitoring is an important issue in the transportation industry. For the case of cementbased structures in particular, detection of corrosion on reinforcing steel bars (rebar) is an ongoing problem for aging infrastructure. There have been a number of techniques that have shown promise in this area including microwave nondestructive testing (NDT) and thermography. Thermogr...

The Brillouin optical time-domain analysis (BOTDA)-based optical fiber method has been proposed to measure strain variations caused by corrosion expansion. Spatial resolutions of 1 m can be achieved with this kind of Brillouin sensor for detecting the distributed strain. However, when the sensing fiber is wound around the steel rebar in a number of circles in a range of several meters, this spa...

The unique self-prestressing behavior exhibited by Iron-based shape memory alloys (Fe-SMAs) coupled with the ease of application makes them suitable for numerous structural applications requiring post-installed reinforcement. However, practical realization Fe-SMA rebars as reinforcement systems entails an understanding their bond concrete to ensure use adequate anchorage length prestress transf...

Two new types of connection between concrete-filled U-shaped steel (CFUS) beams and square tube (CFSST) columns were presented in this study, including rebar-sleeve with internal diaphragm rebar-through connection. Based on the experiments rebar-plate connections CFUS CFSST under cyclic loading, nonlinear finite element models tested specimens developed validated by comparing them experimental ...

Macrocell corrosion of steel rebar in concrete induced by corrosive environments has attracted widespread attention the engineering community due to its rapid rate, diverse forms, and multiple incentives. Potential differences between dissimilar coupled or different parts same mainly cause macrocell rebar. The more significant potential difference, faster rate macrocell. Based on existing resea...

Surface nanocrystallization (SNC) modification can be used to realize the high-efficiency derusting of rusted Cr-alloyed rebar and obtain nanostructured grains on surface rebar. The corrosion resistance performance SNC in a simulated Cl--containing concrete pore solution was evaluated basis electrochemical experiments. Potentiodynamic polarization testing showed that passivation current density...
