Fiber Reinforced Polymer (FRP) bridge systems are gaining wide acceptance among bridge engineers. At the same time, FRP bridge systems are relatively expensive when compared to traditional reinforced concrete bridge systems. In this study, the concept of the hybrid FRP-concrete structural systems is applied to a bridge superstructure. The hybrid FRP-concrete superstructure system is intended to...
Vibrio harveyi luciferase and flavin reductase FRP are, together, a two-component monooxygenase couple. The reduced flavin mononucleotide (FMNH2) generated by FRP must be supplied, through either free diffusion or direct transfer, to luciferase as a substrate. In contrast, single-component bifunctional monooxygenases each contains a bound flavin cofactor and does not require any flavin addition...
In this paper, we demonstrate how Functional Reactive Programming (FRP), a framework for the description of interactive systems, can be extended to encompass parallel systems. FRP is based on Haskell, a purely functional programming language, and incorporates the concepts of time variation and reactivity. Parallel FRP serves as a declarative system model that may be transformed into a parallel ...
The behavior of concrete-filled fiber tubes (CFFT) polymers under axial compressive loading was investigated. Unlike the traditional fiber reinforced polymers (FRP) such as carbon, glass, aramid, etc., the FRP tubes in this study were designed using large rupture strains FRP which are made of recycled materials such as plastic bottles; hence, large rupture strain (LRS) FRP composites are enviro...
The concept of an integrated strengthening and damping retrofit system was proposed to design reinforced concrete (RC) columns for their optimal performance under multi-level earthquake hazards. As illustrated in Figure 1, the system consisted of fiber reinforced polymer (FRP) sheets wrapping around a column and viscoelastic (VE) layers on the FRP sheets. The motion of the outer surface of the ...
During the past decades, FRP strengthened RC structures have attracted worldwide interest in both application and research. Nowadays, as more and more infrastructures are being suffered from severe corrosions due to harsh and extreme environments, the durability of FRP strengthened RC structures has generally emerged as the most important issue in research. Thus, the paper presents the latest p...
Concrete columns confined with high-strength fiber reinforced polymer (FRP) composites can enhance the strength as well as the ductility of such structures. In recent years, the use of FRP composites to repair and strengthen existing reinforced concrete (RC) structures has been widely used. When the columns of existing RC structures are wrapped with FRP composites, the core concrete of such col...
یکی از متداول ترین روش های تقویت سازه های بتن آرمه، استفاده از ورق های تقویتی frp جهت بالابردن مقاومت خمشی و برشی اعضای بتنی می باشد. به دلیل مقاومت بالا، سبکی، اجرای ساده و مقاوم بودن در برابر خوردگی، استفاده از این مصالح روز به روز گسترش بیش تری پیدا کرده است. ضریب پواسون ورق های frp با بتن تفاوت زیادی دارد؛ که این مسئله منجر به جدا شدگی سریع صفحات تقویتی از سطح بتن می شود. آماده نمودن سطح بت...
Thin laminates made of high-strength pultruded fiber reinforced polymers (FRP) are increasingly being used to reinforce glue-laminated timber (glulam) beams, creating a new composite glulam (FRP glulam) significantly stronger in bending than a conventional (unreinforced) glulam of equal size. Large timber members have long been recognized for maintaining structural integrity in fires and this p...
تسلیح خارجی (EBR) روشی مرسوم برای تقویت خمشی تیرهای بتنی با ورقهای FRP میباشد. در این تحقیق تقویت خمشی تیرهای بتن مسلح با استفاده از ورقهای CFRP مورد بررسی قرار میگیرد. 8 نمونه تیر آزمایشگاهی به ابعاد مقطع 300×250 میلیمتر و طول 2200 میلیمتر با درصدهای مختلف فولاد کششی (مقطع با فولادکم و زیاد) به روش EBR تقویت شد و به صورت دو سر ساده و تحت خمش چهار نقطهای مورد آزمایش قرار گرفت. 4 نمونه ...
