Beam tests for verification of performance, and wash-out tests for continuous monitoring of uniform fibre distribution is foreseen. This project was completed in the to period.

Essential properties of steel-fibre-reinforced concrete are its dhv-merkblatt material behaviour and its ability, in case of cracking, to assure load transfer across the crack. Numerous tunnel projects around the world have been implemented using steel-fibre-reinforced concrete segmental linings in recent dvv-merkblatt. In addition, the same load level as with the conventional reinforcement alternative was also achieved.

Local additional reinforcement was incorporated dbv-merkblattt the transverse joints, in view of the extremely high tensile splitting forces occurring at the connecting points of the individual segments.

In addition, the load taken up borne directly by the rock itself is also increased in the case of more flexible systems. Test specimen are stahlfaserrbeton tested by means of deflection-controlled test setups. Write a review Rate this item: Extremely demanding durability requirements were defined in the invitation to tender for this project.

The various problems associated with steel fibres such as e. There is no technological justification for this omission, in view of the fact that both theoretical and practical experience is available. Continuous quality control is being done to check the performance at defined intervals.

Interest in the use of steel-fibre-reinforced concrete in tunnel construction is rising as a result of the flexibility which the use of this material permits and the cost-savings achieved compared to the use of conventional reinforced-concrete solutions. Assessment at international level indicates that reference projects using steel-fibre-reinforced concrete stahlfaserrbeton a permanent load-bearing support element remain far too rare in Germany. And, in case of combination reinforcement, for example, the rebar reinforcement is better protected.

In the case of steel-fibre-reinforced concrete for shotcrete, the steel fibres are added to the basic shotcrete concrete mix. Please re-enter recipient e-mail address es.

In many cases, the load-bearing capacity is sufficient to eliminate entirely the need for the traditional reinforcement which otherwise would be necessary. The influence of the fibres on the strength of concrete is tested on a stahlfsserbeton concrete, in order to provide the user with an idea of the performance of individual fibre types.

Electronic books The e-book database EBC. The materials properties of steel-fibre-reinforced concrete are suitable in two ways for meeting the required load-bearing capacity: Don’t have an account?

The advantage of steel-fibre-reinforced concrete segments over conventional reinforced concrete is that fibres are dispersed all over the section and hence the concrete is also there needled where those critical corner stahlfaesrbeton edge zones are to be found.

Limit the search to the library catalogue. Unlike the situation with non-reinforced concrete mathematical assumption of tensile forces not allowablethis results in a significant increase in load-bearing capacity in structures exposed to bending requirements with normal forces.

Cbv-merkblatt fundamental principles of beam tests are examined in the following sub-section. The concept of using a high-performance steel-fibre-reinforced concrete was, therefore, a relatively obvious step. DBVBerlin; It is therefore primarily used in elements which permit redistribution of internal forces, and therefore multiple crack-formation i.

The resulting stressess determined on this way are lower than in the case of a purely elastic analysis.
