  • Analysis Of Lap Splice Reinforce

    and steel is a major to transfer the load to any structure. The decrease in bond strength between the concrete and steel leads to the failure of the structural member. Lap splice of steel is the common connection n to transfer the loads from one steel bar to another to which it is connected. Fiber reinforced polymer is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass, carbon, aramid, or basalt. In structural members like a beam, columns and slab lap splice are the critical location from where the failure is possible in small loading. Cyclic loading results in the deterioration of structures by decreasing the bond strength, resulting in increased in deflection, number and width of cracks. There are two modes of failure: splitting and pullout (Orangun et al.1977; Eligehausen et al.1983; ACI 2003). When the concrete cover and confinement of concrete is insufficient the splitting failure occurs whereas when the confinement is high enough with large concrete cover then pullout failure occurs. Splitting failure occurs suddenly and the pullout failure occurs gradually and takes time for complete failure. FRP composite materials are comprised of high strength continuous fibers, such as glass, carbon, or steel wires, embedded in a polymer matrix. This is used to increase the bond strength of the splice joint. Many researchers have concluded that use of FRP increase the bond strength, ductility and can withstand large deformation.…

  • Knee Injury Advantages And Disadvantages

    Knee Wraps: The Benefits and Drawbacks What are knee wraps? The knee wrap is similar to the wrist wrap regarding the logic that applies to both. Knee wraps are also to an “Ace” bandage, except that they are much thicker and stronger. The elastic material that is used to make the knee wrap is the same found in wrist wraps. The allowed width for knee wraps is 8 cm (3 inches), although they can sometimes be 2.0 meter, 2.5 meters or even 3.5 meters long. Advantages of using knee wraps The primary…

  • Compare And Contrast Egyptian Cotton Vs Bamboo Sheets

    Egyptian Cotton vs. Bamboo Bed Sheets Egyptian cotton or bamboo bed sheets, which is better? On one hand, Egyptian cotton sheets are well established as the epitome of luxury while bamboo sheets are still fairly new to the world of bedding. On the other hand, bamboo sheets have some unique properties, giving it a competitive edge. So, when you’re shopping for a new set of sheets, should you opt for Egyptian cotton or bamboo? To answer this question, we’ve compared Egyptian cotton to bamboo…

  • Northrop Grumman Case Study

    Virginia Commonwealth State Agency-Northrop Grumman Critical System Outage The commonwealth of Virginia experienced an information technology storage area network outage on August 25th 2010. This affected several agencies and caused 13% of the file servers to fail. The failure mainly impacted the Department of Motor Vehicles and Department of taxation. Because of the outage problem, DMV couldn’t process driver’s licenses and couldn’t share data with other agencies. (1) DMV has been unable to…

  • Case Study: Nanocomposite And Nannofiller

    2.1 Nanocomposite and nanofiller Composite is the combination of two or more different materials that are mixed together in order to bring out the best properties of both material. A nanocomposite is the composite which exhibit at least one dimension of the nanoparticle size material [17]. The nanoparticle size is mainly used as the disperse particle system to enhance or improve the properties of the composite material such as strength, conductivity and wear resistance. The main reason for…

  • The Aerospace Industry

    Aeronautical materials must possess a high Young’s modulus to prevent shape deformation under stress, high resistance to chemical and thermal degradation, high glass transition temperature (Tg), impact strength, amongst numerous others which are more task specific.3 Advancements in polymer chemistry have resulted in a large number of aircraft moving from metallic materials to composite for their primary structures. The definition of a composite states that it is a new material with superior…

  • Dental Hygienist Research Papers

    The repair of dental caries is one of the most frequent procedures performed in the dental office. Even patients that regularly visit the dentist and receive routine cleanings are likely at some point to require a repair of dental caries or fillings. It is estimated that caries affect 60 to 90% of school children, the majority of adults, and their repair occupies most of a dentist’s time.1, 2 The management of caries is relatively standardized across dental offices. It involves making an…

  • The Similarities And Differences Of Terrazzo, Composites, And Composites

    Terrazzo, composites, and concrete are all materials that can be used in the interior of a space. In this paper, I am going to explain the similarities and differences between concrete and terrazzo, what each material is composed of, how these materials are used, and the different subcategories of each material. I’m also going to discuss how each material can be altered, in terms of the look and feel of it. Composite flooring is composed of aggregate and a binder, also known as the matrix. The…
