Prestressed concrete decks are commonly used for bridges with spans between 25m and m and provide economic, durable and aesthetic solutions in most situations where bridges are needed. Concrete remains the most common material for bridge construction around the world, and prestressed concrete is frequently the material of choice.

Concrete has been in use as a primary building material since Roman times.

Prestressed Concrete Bridges, Second edition, is the comprehensive reference for practising bridge engineers on the design and construction of prestressed concrete bridges. Offering complete coverage of the design and construction of prestressed concrete bridges in a single resource, this book is an essential aid for maximising your efficiency on projects and expanding your existing knowledge. The book covers all types of deck arrangements and construction techniques - including in-situ slabs, precast beams, segmental construction, launched bridges and cable-stayed structures - and illustrates the interaction between design and construction. Outlines the fundamentals of the design of prestressed concrete bridges, presenting the latest analysis methods and design techniques. Fully updated for bridge design to Eurocodes.

Prestressed concrete

In the field of bridge engineering, the introduction of prestressed concrete has aided the construction of long-span concrete bridges. These often comprise precast units, lifted into position and then tensioned against the units already in place, the process being continued until the span is complete. For smaller bridges, the use of simply supported precast prestressed concrete beams has proved an economical form of construction. The introduction of ranges of standard beam section has simplified the design and construction of these bridges. Post-tensioning is a method of prestressing in which the tendon is tensioned after the concrete has reached a suitable strength.

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" compressed during production, in a manner that strengthens it against tensile forces which will exist when in service. This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Prestressed concrete is used in a wide range of building and civil structures where its improved performance can allow for longer spans , reduced structural thicknesses, and material savings compared with simple reinforced concrete. Typical applications include high-rise buildings , residential slabs, foundation systems , bridge and dam structures, silos and tanks , industrial pavements and nuclear containment structures.

Они долетали до нее из вентиляционного люка, расположенного внизу, почти у пола. Сьюзан закрыла дверь и подошла ближе. Голоса заглушал шум генераторов. Казалось, говорившие находились этажом ниже. Один голос был резкий, сердитый. Похоже, он принадлежал Филу Чатрукьяну. - Ты мне не веришь.

Prestressed Concrete Bridges - Nigel Hewson

ВЫ УВЕРЕНЫ. Он снова ответил Да. Мгновение спустя компьютер подал звуковой сигнал. СЛЕДОПЫТ ОТОЗВАН Хейл улыбнулся. Компьютер только что отдал ее Следопыту команду самоуничтожиться раньше времени, так что ей не удастся найти то, что она ищет.

Волосы… - Не успев договорить, он понял, что совершил ошибку.

Упираясь ногами в толстый ковер, Сьюзан начала изо всех сил толкать стол в направлении стеклянной двери. Ролики хорошо крутились, и стол набирал скорость. Уже на середине комнаты она основательно разогналась. За полтора метра до стеклянной двери Сьюзан отпрянула в сторону и зажмурилась. Раздался страшный треск, и стеклянная панель обдала ее дождем осколков.

Он никогда не думал, что четыре слова могут сделать его таким счастливым: IM GLAD WE MET Что означало: Я рада, что мы встретились.
