This paper presents a method of analysis for the response of concrete beams reinforced with fibrereinforced-plastic (FRP) tension rods and aramid spirals. Three different kinds of longitudinal reinforcement are adopted; CFRP, AFRP and GFRP. Both under-reinforced and over-reinforced sections are described. It is found that the ratio of neutral axis depth and effective depth can be used as an ind...

Fiber reinforced Polymers (FRP) have widely used for the purposes of enhances strength and ductility of concrete columns. Proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with FRP. In this paper, the influence of FRP thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...

Functional reactive programming facilitates programming with time-varying data that can be perceived as streams flowing through time. Thus, one can think of FRP as an inversion of flow control from the structure of the program to the structure of the data itself. In a typical (say, imperative) program, the structure of the program governs how the program will behave over time; as time moves for...

Saito et al. (Modern Plastics 1997;74:175-7) have developed a low-cost transtibial prosthesis made of fiber-reinforced plastic (FRP). The prosthesis is comprised of an aluminum pylon, a cosmetic cover, and a constant cross-section composite foot into which aluminum supports are screwed to increase load-bearing capacity. Replacing these supports with a single integrated FRP stiffener significant...

We describe a language-centric approach to solving the complex, low-level, and error-prone problem of network control. Specifically, we have designed a domain-specific language called Nettle, embedded in Haskell, that allows programming OpenFlow networks in an elegant, declarative style. Nettle is based on the principles of functional reactive programming (FRP), and as such has both continuous ...

Abstract Hybrid laminates with continuous fiber reinforcement, such as glass reinforced aluminium laminate (GLARE), aramid aluminum (ARALL), or carbon (CARALL), have been developed to increase the lightweight potential and fatigue resistance applied for aircraft structures. However, use of thermosetting matrices imposes material limitations regarding recycling, malleability, manufacturing-cycle...

A series of structural tests were conducted to examine the seismic performance masonry infills strengthened with particular materials on infilled reinforced concrete (RC) frame structures. Six 1:4 scaled-down RC specimens had been prepared, including one brick-infilled without strengthening and five brick innovative materials. The steel wire mesh, chicken hexagonal plastic fiber-reinforced poly...

Fine roots (FR) play a major role in the water and nutrient uptake of plants and contribute significantly to the carbon and nutrient cycles of ecosystems through their annual production and turnover. FR growth dynamics were studied to understand the endogenous and exogenous factors driving these processes in a 14-year-old plantation of rubber trees located in eastern Thailand. FR dynamics were ...
