TL;DR: In this paper, the impact performance of concrete columns confined with fiber reinforced polymer (FRP) jackets was investigated. And the impact duration of concrete specimens confined with LRS FRP was longer than that of the AFRP-confined concrete column.

TL;DR: In this article, the authors numerically investigated the dynamic responses of hybrid DSTC under lateral impact, including bending moment and shear force distributions at typical cross sections, and the impact resistance (shear and flexure) from each component (FRP tube, concrete, and steel tube) was investigated.

TL;DR: In this article, the effects of the fiber-reinforced polymer (FRP) types, FRP confinement stiffness, and strain rate on the impact resistance of high-strength concrete were investigated.

TL;DR: In this paper, a novel environmental fatigue test method was proposed to investigate the fatigue behavior of reinforced concrete (RC) members of highway bridges, which is heavily influenced by service environmental attacks and vehicle random loads, and the results showed that coupling action of hot-wet environment and vehiclerandom load has a significant effect on the fatigue failure mode (including tensile rebar fracture and CFL debonding), fatigue stiffness and fatigue lives of the strengthened beams.

TL;DR: In this article, the axially compressive behavior of circular concrete columns partially wrapped with fiber reinforced polymer (FRP) strips is investigated and compared with the predictions from a typical analysis-oriented stress-strain model to examine its reliability and accuracy.
