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...

We describe a language-centric approach to solving the complex, low-level, and error-prone nature 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 designed in layers to accommodate a family of DSLs targeted for specific network applications. The ...

in this paper, nonlinear behavior of composite steel plate shear wall systems, in which steel infill plate is strengthened by fiber reinforced polymer (frp) layers, are experimentally investigated. tests are designed to evaluate the effect of glass-frp layers, layers number of gfrp and orientation of gfrp layers on the stiffness, shear strength, cumulative dissipated energy and other seismic pa...

This study examines the behavior of circular concretes externally confined by green sustainable WHBR FRP containing water hyacinth fiber ropes and bio-resin. principally purposes to discover axial stress-strain relationship FRP-confined concrete. A total 10 with a dimension 150×300 mm were cast, strengthened one four layers FRP, tested under compression. The stress deformability observed be inc...

design of bridge deck with long-term strength, durability and permanence is a significant interest for engineers. one applicable solution to this challenge could be via using hybrid system consisting of conventional materials such as concrete and steel with frp plates which is also known as composite deck. since these deck are relatively new so their performance is not completely known. the pre...

The static behavior of reinforced concrete (RC) beams plated with layers of fiber-reinforced composite material (FRP) is widely investigated in current literature, which deals with both its numerical modeling as well as experiments. Scientific interest in this topic is explained by the increasing widespread use of composite materials in retrofitting techniques, as well as the consolidation and ...

one important application of fiber reinforced polymer (frp) is to confine concrete as frp jackets in seismic retrofit process of reinforced concrete structures. confinement can improve concrete properties such as compressive strength and ultimate axial strain. for the safe and economic design of frp jackets, the stress-strain behavior of frp-confined concrete under monotonic and cyclic compress...

Restoring forces, which are generated when the left ventricle contracts below its equilibrium volume (Veq), are responsible for diastolic suction. Their magnitude is inversely related to end-systolic volume (ESV). In previous studies in which the mitral valve was replaced with a prosthesis, increased contractility was shown to augment restoring forces independently of ESV. In the present study,...

The aim of this study is to investigate the influence fiber reinforcement polymer (FRP) on shear behavior concrete (RC) beams with various guidelines. FRP thickness, beam depth and strength at ultimate load are considered as main parameters. A finite element (FE) by using ANSYS computer program was used analyze reinforced beams. numerical models were effect depth, strength, CFRP sheet configura...

Among the atmospheric emission sources, wildfires are episodic events characterized by large spatial and temporal variability. Therefore, accurate information on gaseous and aerosol emissions from fires for specific regions and seasons is critical for air quality forecasts. The Spinning Enhanced Visible and Infrared Imager (SEVIRI) in geostationary orbit provides fire observations over Africa a...
