The critical load case in serviceability limit state was determined. Two deformation zones are generally evaluated. DBVBerlin; Search WorldCat Find items in libraries near you. Early application of the initial support, combined with the strength of steel-fibre-reinforced concrete at young age, reduces ground disintegration phenomena and, as a corollary, xtahlfaserbeton overburden stahlfqserbeton, achieving a significantly better stress state.

Don’t have an account? The drafting of the concrete recipe was a real concrete technology challenge, since it was necessary to meet both elevated durability requirements and to counteract the aggressiveness of the groundwater in the geology. Browse subjects Browse through journals Browse through conferences. The use of steel-fibre-reinforced concrete significantly accelerated the construction process. The Hofoldinger Stollen In Germany, a The steel-fibre-reinforced concrete lining segments are being dbv-merklatt as temporary support for the station bores for a service period of three years.

The stiffer the systems, the more greatly they attract bending moments.

The forces to be absorbed by the support segmental lining rings are therefore lower in the case of ductile systems. Plastic analysis comprises the load-bearing capability of steel-fibre-reinforced concrete most rationally. By means of the available stahlcaserbeton methods it is sometimes hardly possible to fugure out the ultimate material resistance, particulary if such elements are exposed to bursting and spalling forces.
