Socio-economic status is a major indicator of livelihood and the two crucial factors determining livelihood are poverty and income inequality. The present study assessed the livelihood status of fishermen operating fibre re-inforced plastic (FRP) boats (motorised) of 9-10 m LOA. Socio-economic status, including poverty and income inequality of fishermen, comprising both owners (FRPO) and labour...
Synopsis: Advantages such as light weight, high mechanical properties and resistance to aggressive and chemical agents, non invasive installation, low tooling and machinery costs, possibility to repair the structure without interrupting its use have determined great expectation on Fiber Reinforced Polymer (FRP) composites for the strengthening of civil structures. However, their diffusion is of...
In recent decades, the application of fibre-reinforced polymer (FRP) composites for strengthening structural elements has become an efficient option to meet the increased cyclic loads or repair due to corrosion or fatigue cracking. Hence, the objective of this study is to explore the existing FRP reinforcing techniques to care for fatigue damaged structural steel elements. This study covers the...
We have developed a domain speci c language for the construction of robot controllers, Frob (Functional ROBotics). The semantic basis for Frob is Functional Reactive Programming, or simply FRP, a purely functional model of continuous time, interactive systems. FRP is built around two basic abstractions: behaviors, values de ned continuously in time, and events, discrete occurances in time. On t...
سازه های بتن آرمه به عنوان بخش گسترده ای از سازه ها چنانچه بر حسب محاسبات دقیق و روابط شکل پذیری طراحی و اجرا شوند ساختمان های بسیار مطلوبی خواهند بود، اما کیفیت ساخت در برخی ساختمان ها به دلایل مختلف بسیار نامطلوب است و همچنین تغییرات آیین نامه ای سبب می شود که این نوع از ساختمان ها نیازمند ترمیم و مقاوم سازی در عصر حاضر باشند. البته این ترمیم و مقاوم سازی می تواند توسط روش های مختلفی صورت گیر...
تعیین مقاومت پیوستگی و طول وصله آرماتورهای پلیمری الیافی (frp) از جمله مسائل مورد بحث پژوهشگران در سال های اخیر است. در این مقاله، رابطه ای برای تعیین طول وصله آرماتورهای frp وصله شده در تیرهای بتن آرمه ارائه می شود. بدین منظور ابتدا به کمک نتایج آزمایش های بیرون کشیدگی سایر محققین ، روابطی برای تعیین مقاومت پیوستگی موضعی و مدول تغییر مکان آرماتورهای frp ارائه می شود. سپس به کمک نتایج آزمایش ها...
FRP (Fire Radiative Power) is the magnitude associated to the thermal radiance which explains the ecological effects of active fire; it is the component of the chemical power released from burning vegetation and emitted as radiation during the process of combustion. In this paper, a discussion of the procedures for active fire FRP is presented: The Dozier method, originally developed for use wi...
Fiber-reinforced polymer (FRP) products are used as an alternative to traditional methods for strengthening and retrofitting concrete and masonry structures to resist blast loads. The development and experimental validation of a methodology for modeling the response of blast loaded concrete and masonry structural components retrofitted with FRP, as well as corresponding response criteria, is im...
Abstract—It is a major challenge to build a bridge superstructure that has long-term durability and low maintenance requirements. A solution to this challenge may be to use new materials or to implement new structural systems. Fiber Reinforced Polymer (FRP) composites have continued to play an important role in solving some of persistent problems in infrastructure applications because of its hi...
In recent years, honeycomb fiber reinforced plastic (FRP) sandwich panels have been increasingly used in various industries. Low weight, low price and high mechanical strength are the benefits of these structures. However, their mechanical properties and behavior have not been fully explored. The objective of this study is to conduct a combined numerical-statistical investigation of honeycomb F...
