4 FRP strengthening systems for infill masonry walls are typically designed to resist flexural stresses due to out-of5 plane pressure. Previous research has shown that there are potential premature failure mechanisms due to shear 6 sliding of the infill, which could reduce the effectiveness of the strengthening system. Current design guidelines for 7 strengthening of masonry walls with fiber-re...
OBJECTIVE To assess the clinical benefit of either metronidazole and amoxicillin or doxycycline administered immediately after completion of full-mouth scaling and root planing (FRP) for treatment of generalized aggressive periodontitis. METHODS Patients, 18 to 40 years of age, referred to the Karadeniz Technical University department of periodontology between January 2009 and September 2009 ...
[1] Instantaneous estimates of the power released by a fire (Fire Radiative Power, FRP) are available with satellite active fire detection products. Integrating FRP in time provides an estimate of the total energy released (Fire Radiative Energy, FRE), which can be converted into burned biomass estimates needed by the atmospheric emissions modeling community. While straightforward in theory, th...
هر چند در سال های اخیر مطالعات زیادی در زمینه مقاوم سازی سازه های بتنی به کمک نوارهای پلیمری انجام شده است اما امروزه ایده کاربرد آن در تقویت سازه های فولادی شکل گرفته است. امروزه تقویت سازه های فلزی عمدتا مشتمل بر جداکردن و جایگذاری صفحه جدید و یا نصب صفحه فلزی جدید بر روی عضو آسیب دیده می باشد در حالیکه این صفحات عمدتا بزرگ و سنگین می باشند و مشکلات بسیاری را از لحاظ نصب و اجرای آن به دنبال د...
خرابی های مشاهده شده در ساختمان ها و پل ها طی زلزله های اتفاق افتاده در طول سالیان، نیاز مبرم به مقاوم سازی سازه ها را نشان می دهد. در دهه اخیر استفاده از کامپوزیت های frp برای مقاوم سازی قاب های بتنی مسلح گسترش یافته است. استفاده از frp به دلیل خصوصیاتی چون مقاومت در برابر خوردگی، وزن کم (نسبت مقاومت به وزن بالا در مقایسه با مصالح سنتی) و مقاومت کششی بالا، در حال افزایش است. یکی از کاربردهای f...
The mechanical behavior of the adhesive interface between the fiber-reinforced polymer (FRP) strip and the concrete substrate often controls the response of FRP-strengthened reinforced concrete (RC) members. Plenty of studies devoted to understanding the mechanical behavior of FRP strips glued to concrete are currently available in the scientific literature. However, they are mainly focused on ...
We present our experiences integrating Functional Reactive Programming (FRP) into a new host language, Python, and a variety of computational contexts: a game engine, a GUI system, and an embedded controller. We demonstrate FRP principles extended to a dynamic environment and the integration of object-oriented libraries into the reactive environment. A number of FRP semantic issues are addresse...
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...
