Prediction of Axial Compressive Strength of Hybrid Reinforced Concrete Columns under Static Loading [PDF]

open access: yesJES: Journal of Engineering Sciences, 2023
Steel corrosion is thought to be one of the primary causes of the inadequate durability of concrete buildings in the maritime environment. Because of this, adopting Fiber-Reinforced Polymer (FRP) bars in harsh settings has attracted a lot of attention ...

Experimental Investigation of Concrete Cylinders Confined with PBO FRCM Exposed to Elevated Temperatures

open access: yesFire, 2023
Externally bonded fiber-reinforced polymers (FRPs) have been widely used for strengthening and retrofitting applications. However, their efficacy is hindered by the poor resistance of their epoxy resins to elevated temperatures and their limited ...
