Abstract
AbstractRecent advancements in material sciences have led to the development of new fiber-reinforced polymer (FRP) systems that, unlike traditional FRPs, are specifically tailored to have large fra...
Highlights
The interest in applying fiber-reinforced polymer (FRP) materials to reinforced concrete (RC) structures to retrofit applications has increased over the last few decades (Hawileh et al 2014)
polyethylene terephthalate (PET)-FRP laminates were tested at distinct temperatures of 25°C, 50°C, 75°C, 100°C, and 125°C to investigate the degradation of its mechanical properties at elevated temperatures
Stress-strain curves were drawn using strains obtained from Digital image correlation (DIC), and the mechanical properties, such as modulus, tensile strength, and Poisson’s ratio, were discussed
Summary
The interest in applying fiber-reinforced polymer (FRP) materials to reinforced concrete (RC) structures to retrofit applications has increased over the last few decades (Hawileh et al 2014). Commonly used FRP strengthening systems are never utilized to their full-strength capacity (Dai et al 2011; Saleem et al 2017) Despite this limitation, numerous studies have indicated that conventional FRP laminates can be successfully used to confine structural elements in seismic applications, increasing their axial and shear strengths. Noted is that high-strength and brittle FRP is never completely utilized to its fullstrength capacity in external strengthening applications (Ali et al 2014; Shekarchi et al 2018). In addition to their desirable mechanical properties, LRS-FRPs have the additional advantage of being more economical and environmentally friendly than conventional FRPs (Borg et al 2016)
