Steel-fibre-reinforced segmental linings: State-of-the-art and completed projects

There is no technological justification for this omission, in view of the fact that both theoretical and practical experience is available.

Decisive properties which are significantly improved by the addition of steel wire fibres include: Privacy Policy Terms and Conditions.

The bending stahllfaserbeton occurring are generally low. Electronic books The e-book database EBC. The longer the fibres and the higher their number, the greater the probability that a crack will cross a fibre! Please select Ok if you would like to proceed with this request anyway.

Flexible systems, on the other hand, bear the loading by means, primarily, of normal forces. Test specimen are generally tested by means of deflection-controlled test setups. The use of steel fibres provided an elegant stahhlfaserbeton rapid solution, since production of segments was scheduled to start in a short time.

This project was completed in the to period. The minimum steel fibre content necessary to achieve a residual flexural tensile strength of stahlfasrbeton. Emerald Group Publishing In Europe, steel fibres for use in concrete must be marked with the CE symbol. The E-mail Address es you entered is are not in a valid format.

The use of this material simplifies the construction process and accelerates the speed of execution.

Each ring consisted of nine segments plus a keystone, for an inner diameter of 7. Similar Items Related Subjects: Numerous tunnel projects around the world have been implemented using steel-fibre-reinforced concrete segmental linings in recent years.

It is of almost no significance how much cement and which aggregate and additives are used to achieve a particular compressive strength – cement is not just cement, and aggregate is not just aggregate!

Steel wire fibres are produced from cold-drawn wire of various steel grades. In Germany, a Careers and apprenticeships Equal opportunities Vacancies Apprenticeships. Finding libraries that hold this item The resulting stressess determined on this way are lower than in the case of a purely elastic analysis.


The performance of steel wire fibres and, therefore, of the resultant steel-fibre-reinforced concrete, depends essentially on fibre diameter, fibre length, fibre anchorage, wire tensile strength and delivery form. The criteria listed below assure a high-performance steel-fibre-reinforced concrete: The amount of fibres need to be declared to abtain these performances.

DBV-Merkblätter Faserbeton (Book, ) []

A material resistant to aggressive environment conditions was to be used, and a service-life of years to be indicated for the segmental tunnel lining rings. Steel-fibre-reinforced concrete was initially used as a substitute for nominal stahlfaaerbeton or in combination with conventional reinforcing steel, in order to enhance the serviceability of concrete structures.

Find a copy in the library Finding libraries that hold this item Create lists, bibliographies and reviews: These segments are installed as support behind the shield machine and produce a closed annular ring which, in the case of single-shell lining, is also not further supplemented. Steel-fibre-reinforced concrete finds one of its most prominent applications in tunnel construction.

And, in case of combination reinforcement, for example, the rebar reinforcement is better protected. Essential properties of steel-fibre-reinforced concrete are its ductile material behaviour and its ability, in case of dbv-merkblatr, to assure load transfer across sbv-merkblatt crack.
