Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) have been developed to reinforce gluelaminated timber (glulam) beams. The FRP reinforced glulams are significantly stiffer, stronger, and have less variation in bending strength than a conventional (unreinforced) glulam of equal size. Following the technical development and model building code approval of design proc...

Tension stiffening behavior of post-cracking concrete is an important phenomenon which has been extensively studied for reinforced concrete structures. Although externally bonded fibre reinforced polymer (FRP) composites are widely used for strengthening existing RC structures, it remains unclear to what extent the tension stiffening of post-cracking concrete is quantitatively influenced by the...

We studied the relationship between the atrioventricular nodal functional refractory period (FRP) and refractoriness by mathematical analysis and by measurement during antegrade Wenckebach cycles in 16 dogs. The FRP relates directly to the conduction time of the control beat, and inversely to the coordinates of the point on the A'-H' vs. A-A refractory curve where the slope is -1. The FRP can v...

Characterising the dynamics of landscape-scale wildfires at very high temporal resolutions is best achieved using observations from Earth Observation (EO) sensors mounted onboard geostationary satellites. As a result, a number of operational active fire products have been developed from the data of such sensors. An example of which are the Fire Radiative Power (FRP) products, the FRP-PIXEL and ...

The Vibrio harveyi NADPH-specific flavin reductase FRP follows a ping-pong mechanism but switches to a sequential mechanism in the luciferase-coupled reaction. The bound FMN co-isolated with FRP, while acting as a genuine cofactor in the single-enzyme reaction, functions in the luciferase-coupled reaction as a prebound substrate and is directly transferred to luciferase once it is reduced [Lei,...

Fiber-reinforced polymer (FRP) has been increasingly applied to steel structures for structural strengthening or crack repair, given its high strength-to-weight ratio and high stiffness-to-weight ratio. Cracks in steel structures are the dominant hidden threats to structural safety. However, it is difficult to monitor structural cracks under FRP coverage and there is little related research. In...

Sprayed FRP is a novel method developed at the University of British Columbia which has been very successful in repairing damaged structures is Sprayed FRP. The key to a successful and optimal usage of FRP in strengthening and rehabilitation is in our ability to understand and effectively engineer SubstrateFRP bond. In this paper, performance of FRP as a repair material is studied by structural...

This paper reports on nine relevant applications of FRP composites in concrete structures in the United States. Strengthening of concrete members with externally bonded FRP laminates or near surface mounted (NSM) bars has received remarkable attention. FRP materials have been used in small projects and some multi-million dollar projects for strengthening parking garages, multi-purpose conventio...
