Epoxy bonded steel plates (externally bonded reinforcemen: EBR) for the strengthening of concrete structures were introduced to the construction industry in the late 1960s, and the use of fibre reinforced polymers (FRPs) was introduced in the 1990s, which means that these techniques have already been used in construction for 50 and 25 years, respectively. In the first part of the paper, a histo...

Corrosion of steel reinforcement in concrete structures and bridges is a major problem facing the departments of transportation worldwide. In the United States, maintenance and replacement costs are measured in billions of dollars. Salt environment in hot climate and the use of deicing salts in cold regions have resulted in steady deterioration of bridge decks due to corrosion. These concerns h...

Owing to the diversity in cause and damage, there is no standard surgical treatment method for a complicated penetrating craniofacial injury. The treatment of a complicated penetrating head injury caused by a steel bar is presented here. A 66-year-old woman fell onto a steel bar at a construction site and it penetrated the mandible, entered the sinus and orbital cavities, and reached the base o...

As a fair deck pavement material of its kind used in steel bridge, the epoxy asphalt concrete is considered much more superior to ordinary asphalt concrete in terms of road performance, while still greatly subject to the level of design and construction. Starting from a practical case of the epoxy asphalt concrete that has been applied in the deck pavement of Pingsheng Steel Bridge, this paper ...

Polymer concrete, a composite material in which the binding material is some type of polymer, is being used more widely in the construction industry. Polymer concretes can also contain steel reinforcing rebars; therefore, the rate of adhesion between polymer concrete and reinforcing steel must be determined. Our study investigated the extent and behaviour of adhesion in the case of reinforcing ...

There are many instances where the use of weight-saving polymer composite material for an entire structure is either too complex, too expensive or unfeasible. In these circumstances the use of a hybrid structure can incorporate the benefits of traditional (e.g. steel ) construction coupled with the advantages of composite materials [e.g. glass-reinforced polymers, glass-reinforced plastic (GRP)...

The Feedback Lap Steel is an actuated instrument that makes use of mechanical vibration of the instruments bridge to excite the strings. A custom bridge mounted directly to a tactile transducer enables the strings to be driven with any audio signal from a standard audio amplifier. The instrument can be played as a traditional lap steel guitar without any changes to playing technique as well as ...

فرآیند نورد تجمعی (accumulative roll bonding (arb)) یکی از رایج ترین روش ها برای تولید مواد ورقه ای فوق ریزدانه شده می باشد. این روش شامل چرخه های مختلفی از نورد، برش و پشته سازی است و تا مرز امکان می تواند تکرار شود. در این تحقیق، کامپوزیت چندلایه al/steel با استفاده از ورق های 1100al- و 12st- به روش arb و تا سه چرخه تولید شد. میکروساختار و خواص مکانیکی کامپوزیت چندلایه al/steel در چرخه های مخ...
