Coupling beams are considered one of the most important structural elements due to their vital role in resisting lateral loads by improving overall building stiffness and reducing impact overturning. The resistance coupled shear walls (CSWs) earthquakes depends on coupling beam (CB) for enhancing ductility system energy absorption capacity. There two main types beams; diagonally reinforced conv...

Abstract This paper presents the results of an experimental study on employing near surface mounted (NSM) fiber-reinforced polymer (FRP) reinforcement technique, and L?shape ribbed bars, for flexural strengthening lightweight reinforced concrete (RC) beams. 18 RC beams including 14 four normal-weight were designed. The strengthened with glass (GFRP) bars carbon (CFRP) laminate in bending tests....

Despite the widespread use of RC continuous beams, performance these when repaired via Fiber Reinforced Polymer (FRP) composite material, has received less attention. Furthermore, several features flexural aspect beams still demand experimental and analytical evaluation. However, many anchoring methods have been developed to delay premature failure in which are strengthened with FRP materials. ...

Fiber reinforced polymer (FRP) composites are getting a wide range of application areas in bridge rehabilitations because these materials are less affected by corrosive environmental conditions, known to provide longer life and require less maintenance. However, there are still some concerns about their long-term performance because currently limited data exists. Moreover, the quality control a...

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...

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...

The use of mechanically-fastened fiber-reinforced polymer (MF-FRP) systems has recently emerged as a competitive solution for the flexural strengthening of reinforced concrete (RC) beams and slabs. An overview of the experimental research has proven the effectiveness and the potentiality of the MF-FRP technique which is particularly suitable for emergency repairs or when the speed of installati...

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...

It is believed that the reduced FMN substrate required by luciferase from luminous bacteria is provided in vivo by NAD(P)H-FMN oxidoreductases (flavin reductases). Our earlier kinetic study indicates a direct flavin cofactor transfer from Vibrio harveyi NADPH-preferring flavin reductase P (FRP(H)) to the luciferase (L(H)) from the same bacterium in the in vitro coupled luminescence reaction. Ki...
