A large database consisting of 832 axial compression tests results of fiber reinforced polymer (FRP)confined concrete specimens was assembled. Using the test database, existing conventional and evolutionary algorithm models developed for FRP-confined concrete were then assessed. New genetic programming (GP) models for predicting the ultimate condition of FRP-confined concrete were developed. Th...

fi ber reinforced plastic (FRP) re. nforcement is one of the most promising new developments for concrete structures. FRP reinforcing elements provide lighter, easier to assemble, and more durable structures that are free of the deterioration caused by corrosion of steel. FRPs consist of synthetic or organic highstrength fibers, most of which are impregnated with a resin matrix. They are availa...

This paper identifies assessment techniques for critical parameters relative to installation and performance of fiber reinforced polymer (FRP) materials as a way to strengthen structurally deficient concrete bridges. Various Nondestructive Testing (NDT) techniques, representing viable solutions for identification and monitoring of such critical parameters on structural members strengthened with...

Basalt continuous fibers are regarded as an inert and naturally occurring material that is produced from basalt rock by using single component raw material and drawing and winding fibers from the melt. Basalt based materials are environmentally friendly and nonhazardous. Basalt FRP (BFRP) composites as a reinforcement not only display a higher strength and modulus, but also a similar cost, and ...

A purely functional model of computation, called Priority-based Functional Reactive Programming (P-FRP), has been introduced as a new paradigm for building real-time software. Unlike the classical preemptive model of real-time systems, preempted events in P-FRP are aborted and have to restart when higher priority events have completed, making the response time of events dependent on the executi...

Study the tensile damage and fracture behavior of FRP composite materials by the acoustic emission technology, broadband sensors record the acoustic emission signals when composite materials in the process of tensile damage at different fiber angle. The acoustic emission characteristics of FRP composite materials’ tensile damage was analyzed by 3D parameter methods. Analysis the amplitude of co...

In this paper, the advances of finite element methods and analyses for FRP reinforced and strengthened concrete beams in last two decades are reviewed to present a state of the art of the research of numerical analysis and modelling of FRP composite concrete beams. Future research on finite element analysis of FRP composite beams is also presented.

To investigate the action of motilin on the sphincter of Oddi, the flow rate of the perfusate (FRP) discharged into the duodenal lumen through the orifice of the common bile duct was measured by means of an electric drop counter in decerebrated dogs. Motilin in doses above 0.5 micrograms/kg i.v. reduced or stopped the FRP. The fifty percent recovery time of FRP was 20 min and full recovery time...

In previous work we presented Functional Reactive Programming (FRP), a general framework for designing hybrid systems and developing domain-specific languages for related domains. FRP’s synchronous dataflow features, like event driven switching, supported by higherorder lazy functional abstractions of Haskell allows rapid development of modular and reusable specifications. In this paper, we wil...

The strengthening of concrete structures externally bonded with fiber reinforced polymer (FRP) sheet is increasingly being used for repair and rehabilitation of existing structures. This paper provides information in the area of long-term durability of FRP-concrete interface externally bonded with FRP composite sheet. It mainly discusses and summarizes the influence of harsh environmental expos...
