Corrosion of steel reinforcement in an aggressive environment constitutes a serious problem for many reinforced concrete (RC) structures. Fiber-reinforced polymers (FRP) rebars represent a potential solution to this situation. Even if FRP reinforcement shows a good resistance to electro-chemical corrosion, long-term behavior must be investigated and proven. The mechanical properties of FRP rods...

Recent research has focused on rehabilhation and strengthening of steel structures and bridges using fiber reinforced polymer (FRP) materials. The bond behavior of FRP materials to steel structures is quite different from lhat of concrete structures. Preliminary test results showed the occurrence of very high bond stresses for most strengthening applications due to the amount of strengthening r...

There is a growing need for the rehabilitation, repair, and upgrading of concrete structures such as bridges and buildings. The repair or rehabilitation of reinforced concrete structures often offers a lower cost alternative to rebuilding, and it is traditionally achieved by bonding steel plates to the tensile face of a reinforced concrete member. The shear strength can be enhanced with plates ...

Objective To evaluate the ability of the eluate from fibrin-rich plasma (FRP) membrane to induce proliferation and differentiation of isolated human adipose-derived stem cells (ASCs) into chondrocytes. Method FRP membranes were obtained by centrifugation of peripheral blood from two healthy donors, cut, and maintained in culture plate wells for 48 h to prepare the fibrin eluate. The SCATh wer...

This paper deals with an experimental study on the tensile performance of recently developed “FRP Hybrid Bars” by authors. The objective of this study is to investigate tensile strength of FRP Hybrid Bars and to overcome the shortcomings of the FRP material with its low elastic modulus. This uses the concept of material hybridization to increase elastic modulus to be used in concrete structures...
