1.1 Background Fibre Reinforced Polymers (FRP’s) have seen active use for strengthening applications in construction since the late 1980’s. They are now securely placed to replace the ageing technologies used in the commonly termed, ‘traditional methods’ of strengthening, which have customarily resulted in an increased cross-section size with the provision of additional reinforced concrete, or ...
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...
Results in the literature demonstrate that substantial improvements in the mechanical behavior of polymers have been attained through the addition of small amounts of carbon nanotubes as a reinforcing phase. This suggests the possibility of new, extremely lightweight carbon nanotube-reinforced polymers with mechanical properties comparable to those of traditional carbon-fiber composites. Motiva...
In recent years, even if Fiber Reinforced Polymer (FRP) composites have been widely used for strengthening of civil buildings, a new generation of materials has been studied and proposed for historical masonry construction. These buildings, mainly made of stone work, are common in many areas of Europe and Asia and recent earthquakes has been the cause of many catastrophic failures. The brittlen...
اتصالات تیر به ستون در قابهای خمشی یکی از کلیدیترین اعضا در مسیر انتقال بارهای جانبی بوده که بروز ضعف در عملکرد آنها سبب انهدام کل سازه میگردد. استفاده از کامپوزیتهای FRP (Fiber Reinforced Polymer) در تقویت و ترمیم این اعضا به عنوان یک راهکار مؤثر جایگاه ویژهای در صنعت ساختمان به خود اختصاص داده است، اما جدا شدگی کامپوزیتهای FRP از سطح بتن به بزرگترین چالش پیش روی محققین تبدیل شده است. ...
Composite materials, comprised of fibre-reinforced polymers, offer a high strength-to-weight ratio, making them excellent for the building complex, lightweight structures in several industries, including marine industry. There is an improvement fuel efficiency and cost-effectiveness general component developments as result flexible design characteristics. Fibre-reinforced polymer (FRP) composit...
Fiber-reinforced polymer (FRP) composites are increasingly used in concrete structures owing to their superior corrosion resistance. However, FRP-reinforced (RC) exhibit less ductile response compared steel RC structures. Recently, the use of basalt fiber reinforced (BFRC) with BFRP bars was investigated achieve a reasonable level ductility BFRC-BFRP one-way slabs. The shear behavior such slab ...
• ساختمان های بتنی طراحی شده بر اساس آیین نامه 2800 و آیین نامه بتن ایران (آبا) ، به روش غیر خطی تحلیل شده و سپس معیارهای پذیرش دستورالعمل بهسازی لرزه ای ایران کنترل می گردد و در صورت نیاز راهکارهای مقاوم سازی برای آنها ارائه می شود. یکی از روشهای مقاوم سازی، استفاده از کامپوزیت های الیافی، frp (fiber reinforced polymer) برای تقویت قسمت های ضعیف سازه است. یکی ازجدیدترین روش های کاربرد frpدر تقو...
