در سال­های اخیر با مطرح شدن بحث تقویت اعضاء بتن مسلح توسط ورق­های FRP فصل جدیدی از مطالعات در این زمینه شکل گرفته است، که بخش قابل توجهی از این مطالعات بر طراحی برشی اعضاء تقویت شده با FRP متمرکز می­باشد. با توجه به نسبت ابعاد تیرهای عمیق و بالا بودن تغییرشکل برشی ضعف عمده تیرهای عمیق را می­توان پائین بودن ظرفیت برشی و به دنبال آن شکست برشی و ضریب شکل پذیری پائین دانست. ، برای تقویت این اعضای ب...

In an attempt to identify autoantigens of synovium in rheumatoid arthritis (RA), we constructed lambda phage expression cDNA libraries from synovium and screened them by IgG purified from synovial fluids, both of which were derived from RA patients. As a result of this unique combination of the libraries and probes, we cloned follistatin-related protein (FRP) as a novel autoantigen in systemic ...

The overall objective of this research project was to conduct an extensive study of the behavior and use of glass fiber-reinforced polymer (GFRP) and carbon FRP (CFRP) materials for bridge construction. In particular, GFRP honeycomb sandwich panels were used as bridge panels and steel-supported bridge deck panels and CFRP and GFRP bars were used as internal reinforcement for precast concrete br...

Functional Reactive Programming (FRP) is a declarative programming model for constructing interactive applications based on a continuous model of time. FRP programs are described in terms of behaviors (continuous, timevarying, reactive values), and events (conditions that occur at discrete points in time). This paper presents Frappé, an implementation of FRP in the Java progamming language. The...

Over the last two decades fiber-reinforced polymer (FRP) rods have emerged as one of the most promising and affordable solutions to the corrosion problems of steel reinforcement in structural concrete. The application of FRP rods in new or damaged structures requires the development of design equations that must take into account the mechanical properties and the durability properties of FRP pr...

This report deals with the experimental investigation of using large deformable FRP, ± 45° oriented fibers, in concrete-filled fiber tubes (CFFT) under axial cyclic compressive loading. In addition, this report presents finite element modeling (FE) of CFFTs with large rupture strain FRP (LRS-FRP). The LRS-FRP is made with polyethylene naphthalate (PEN) and polyethylene terephthalate (PET) fiber...

پلها به لحاظ رفتار و پاسخ سازه ای در مقایسه با سازه های معمولی در موقعیت ویژه ای قرار دارند با توجه به آنکه درجه نامعینی پلها به نسبت ساختمانها بسیار کمتر می باشد، شکست یک ستون می تواند منجر به خرابی کل سیستم سازه گردد. با توجه به آنکه پل به عنوان یک شریان حیاتی در صنعت حمل ونقل مطرح می باشد ، فراهم آوردن امنیت لرزه ای کافی برای آن از درجه اهمیت بالایی برخوردار است. ستون بتن آرمه پل در اثر باره...

Debonding problems of externally bonded fiber reinforced polymer (FRP) sheets in flexurally FRP-strengthened reinforced concrete (RC) beams have been a concern and a research challenge since their application of this strengthening technique. Intermediate crack induced debonding is the most common failure mode which is that the debonding initiates at the critical flexural-shear or flexural crack...

Functional Reactive Programming (FRP) is a high-level declarative language for programming reactive systems. Previous work on FRP has demonstrated its utility in a wide range of application domains, including animation, graphical user interfaces, and robotics. FRP has an elegant continuous-time denotational semantics. However, it guarantees no bounds on execution time or space, thus making it u...

Functional Reactive Programming (FRP) is a programming framework for constructing interactive applications in a declarative manner. FRP is now used in animation, vision, robotics and other control systems. Behaviors and Events – values and conditions which are functions of time – play a key role in FRP. In this paper we present an implementation of main FRP features in C++, an widely used imper...
