GFRP Reinforcement in Concrete after 15 Years of Service

AbstractGlass fiber–reinforced polymer (GFRP) composite bar is emerging as a feasible and economical solution to eliminate the corrosion problem of steel reinforcements in concrete structures; thus...

Post-fire behavior of GFRP bars and GFRP-RC slabs

AbstractTechnologies developed over the last two decades have introduced the use of glass fiber reinforced polymer (GFRP) composite bars as reinforcement in concrete structures when corrosion of th...

Microstructure and Mechanical Property Behavior of FRP Reinforcement Autopsied from Bridge Structures Subjected to In Situ Exposure

This paper examines the microstructure and mechanical property behavior of FRP reinforcement extracted from several FRP-reinforced concrete bridges built more than a decade ago. These include bridges constructed in Missouri and Texas. In particular, the following tests were performed including SEM, FTIR, EDX, glass transition temperature (Tg), and short shear test (SBS). Results from the evaluation demonstrated that the FRP bars are performing at a level with no observed degradation. The paper collects data to study the implications of the current ACI code knockdown factors relative to field-related data.
