Reinforced concrete , Concrete in which steel is embedded in such a manner that the two materials act together in resisting forces. The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure. Plain concrete does not easily withstand tensile and shear stresses caused by wind, earthquakes, vibrations, and other forces and is therefore unsuitable in most structural applications.

In reinforced concrete, the tensile strength of steel and the compressive strength of concrete work together to allow the member to sustain these stresses over considerable spans. Reinforced concrete. Article Media. Info Print Cite. Submit Feedback. Thank you for your feedback.

Reinforced concrete RC also called reinforced cement concrete or RCC is a composite material in which concrete 's relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars rebar and is usually embedded passively in the concrete before the concrete sets. Modern reinforced concrete can contain varied reinforcing materials made of steel, polymers or alternate composite material in conjunction with rebar or not. Reinforced concrete may also be permanently stressed concrete in compression, reinforcement in tension , so as to improve the behaviour of the final structure under working loads.

The size of buildings in the commercial, institutional, and industrial market segment ranges from a few hundred to as much as 45, square metres , square feet. All of these buildings have public access and exit requirements, although their populations may differ considerably in density. The unit costs are generally higher than those for dwellings although those of simple industrial buildings may be lower , and this type includes buildings with the highest unit cost, such as hospitals and laboratories. Residential buildings are fairly static in their function, changing only at long intervals. By contrast, most commercial, institutional, and industrial buildings must respond to fairly rapid changes in their functions, and a degree of flexibility is required in their component systems. In addition, these buildings are built by contractors who utilize heavy mechanized equipment not only for foundations pile drivers and caisson augers but also for lifting heavy components a wide variety of cranes and hoists. Semimanual machines such as cement finishers, terrazzo grinders, and welding generators are also used, but a large percentage of the work is done manually; the human hand and back remain major instruments of the construction industry , well adapted to the nonrepetitive character of building. The foundations in these buildings support considerably heavier loads than those of residential buildings. Floor loadings range from to 1, kilograms per square metre to pounds per square foot , and the full range of foundation types is used for them.

As the electrode melts, it supplies weld material which fuses the pieces of steel together. The Architect is usually employed by and represents the Owner. Tendons in the perpendicular direction are spaced uniformly. Bar numbers are rolled onto the bar for easy identification.

Construction workers build, repair, maintain, renovate, modify and demolish houses, office buildings, temples, factories, hospitals, roads, bridges, tunnels, stadiums, docks, airports and more. The International Labour Organization ILO classifies the construction industry as government and private-sector firms erecting buildings for habitation or for commercial purposes and public works such as roads, bridges, tunnels, dams or airports. In the United States and some other countries, construction workers also clean hazardous waste sites.

Beginning on July 1, , manufacturers and certain research and developers may qualify for a partial exemption of sales and use tax on certain manufacturing and research and development equipment purchases and leases. To be eligible for this partial exemption, you must meet all three of these conditions:. Our tax and fee laws can be complex and difficult to understand. If you have specific questions about this exemption and who or what qualifies, we recommend that you get answers in writing from us. This will enable us to give you the best advice and will protect you from tax, penalties and interest in case we give you erroneous information.

S tonehenge in England, the Great Pyramid of Giza, the Peruvian citadel at Machu Picchu—three wondrous examples of how stone structures can last hundreds or even thousands of years. But though stone is one of the oldest and most durable building materials, it isn't exactly easy to work with. It's heavy, hard to transport, and usually comes in giant chunks, which have to be laboriously cut to shape.

Reinforced Concrete Terminology

Thousands of years ago, pre-humans built the first bridge. It was a simple log or boulder placed over a small stream or ravine. It would have helped keep the feet of nomads dry while traveling from one location to another. Bridges have gotten much more complicated since then.

Concrete and reinforced concrete

This article presents information necessary to assist in the choice and use of steel structures at the concept design stage for modern multi-storey buildings and single storey buildings. The information is presented in terms of the design strategy, anatomy of building design and structural systems. For multi-storey buildings the primary sector of interest is commercial buildings, but the same information may also be used in other sectors.

Reinforced concrete, or RCC, is concrete that contains embedded steel bars, plates, or fibers that strengthen the material. Register for Member Meetings.

ТРАНСТЕКСТ появился на свет. Хотя создававшийся в обстановке повышенной секретности ТРАНСТЕКСТ стал плодом усилий многих умов и принцип его работы не был доступен ни одному человеку в отдельности, он, в сущности, был довольно прост: множество рук делают груз легким. Три миллиона процессоров работали параллельно - считая с неимоверной скоростью, перебирая все мыслимые комбинации символов.

Надежда возлагалась на то, что шифры даже с самыми длинными ключами не устоят перед исключительной настойчивостью ТРАНСТЕКСТА. Этот многомиллиардный шедевр использовал преимущество параллельной обработки данных, а также некоторые секретные достижения в оценке открытого текста для определения возможных ключей и взламывания шифров.

Я хотел уйти с сознанием, что добился своей цели. - Но вы добились своей цели, - словно со стороны услышала Сьюзан собственный голос, - Вы создали ТРАНСТЕКСТ. Казалось, Стратмор ее не слышал. - В последние несколько лет наша работа здесь, в агентстве, становилась все более трудной.

Мы столкнулись с врагами, которые, как мне казалось, никогда не посмеют бросить нам вызов. Я говорю о наших собственных гражданах.

Быстрым движением Халохот подтащил его к скамье, стараясь успеть, прежде чем на спине проступят кровавые пятна. Шедшие мимо люди оборачивались, но Халохот не обращал на них внимания: еще секунда, и он исчезнет. Он ощупал пальцы жертвы, но не обнаружил никакого кольца.
