This report deals with the experimental investigation of using large deformable FRP, ± 45° oriented fibers, in concrete-filled fiber tubes (CFFT) under axial cyclic compressive loading. In addition, this report presents finite element modeling (FE) of CFFTs with large rupture strain FRP (LRS-FRP). The LRS-FRP is made with polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) fiber...

Debonding problems of externally bonded fiber reinforced polymer (FRP) sheets in flexurally FRP-strengthened reinforced concrete (RC) beams have been a concern and a research challenge since their application of this strengthening technique. Intermediate crack induced debonding is the most common failure mode which is that the debonding initiates at the critical flexural-shear or flexural crack...

Functional Reactive Programming (FRP) is a high-level declarative language for programming reactive systems. Previous work on FRP has demonstrated its utility in a wide range of application domains, including animation, graphical user interfaces, and robotics. FRP has an elegant continuous-time denotational semantics. However, it guarantees no bounds on execution time or space, thus making it u...

Functional Reactive Programming (FRP) is a programming framework for constructing interactive applications in a declarative manner. FRP is now used in animation, vision, robotics and other control systems. Behaviors and Events – values and conditions which are functions of time – play a key role in FRP. In this paper we present an implementation of main FRP features in C++, an widely used imper...

The overall objective of this research project was to conduct an extensive study of the behavior and use of glass fiber-reinforced polymer (GFRP) and carbon FRP (CFRP) materials for bridge construction. In particular, GFRP honeycomb sandwich panels were used as bridge panels and steel-supported bridge deck panels and CFRP and GFRP bars were used as internal reinforcement for precast concrete br...

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...
