Abstract: Numerous reinforced concrete frames have collapsed in major earthquakes because of severe local damage at the ends of columns. Many of these frames were designed and built according to out-of-date codes in which earthquake ...

Abstract: For the seismic design of fiber reinforcement polymer (FRP) confined reinforced concrete (RC) columns, the development of an accurate axial stress-strain model that considers cyclic compression is necessary. In light of ...

Abstract: The majority of experimental studies investigating the stress-strain behavior of square concrete columns confined with carbon fiber-reinforced polymer (CFRP) composites have focused largely on unreinforced columns of small ...

Abstract: Although graphene oxide (GO) can be well dispersed in water, it tends to reagglomerate in an alkaline cement hydration environment, thus seriously degrading the workability and mechanical strength of the mixture. This study ...
