Definitions

  • Structurally loaded structures are usually designed in their design that they any negative environmental influences, such as increased temperature load on occurrence withstand a fire for at least some time.
  • tunneling elements on their surface with Thermal insulation mat lined to the heating of the tunnel shell in a fire delay for example tunneling elements on their surface with Thermal insulation mat lined to the heating of the tunnel shell in a fire delay.
  • the present invention sets the task To develop computational methods, which without application of complex numerical Methods works and a load-bearing proof of statically charged Concrete structures during and after a fire.
  • the fire load either predefined fire courses or especially for fire load curves calculated in each case, in which case the nature of the Transport or goods transported. Determine these fire load curves the temperature curve as a function of time.
  • the material characteristics for the component in the case of a tunnel for reinforced concrete, under the influence of temperature. These are the properties during the Fire and residual strength after firing for both concrete and steel certainly.
  • the prerequisite for this is that the inner reinforcement layer is protected accordingly is. If the inner, the temperature-exposed reinforcement layer is not against overheating protected, so there is no residual strength and thus no carrying capacity is obtained.
  • the protection Reinforcement can only be achieved by correspondingly large coverage.
  • the Preventing the peeling of the cover either by skin reinforcement or by the Addition of polypropylene fibers is of great importance.
  • the carrying capacity of the individual cross section depends from the definition of the marginal expansions, whereby here in particular the increase of the admissible Concrete compression makes a significant contribution.
  • the definition of the limit strains has all influence with temperature-loaded cross sections.
  • the temperature stress leads to a reduction of the total Bearing capacity of the cross-section and at the same time to an asymmetrical load-bearing behavior of the cross section, since the material properties themselves for geometrically symmetric Cross sections are now asymmetrical.
  • Linear linear statics only allow linear gradients of temperature gradients. As could be detected, the actual temperature gradients deviate greatly from linear courses. As a rule, the edge zones are heavily stressed by temperature, further internal cross-sectional parts and the part facing away from the fire Cross-section are usually hardly or not at all temperature-stressed.
  • an internal load can be applied to any temperature load Stress condition can be defined, at each point on the one hand by the respective prevailing temperature and the resulting strains is determined. on the other hand
  • the material properties can be dependent on the temperature be defined, bringing the total load from the given temperature gradient calculates.
  • the fire load is set constant around the tunnel cross section. As the fire duration increases, the temperature stress penetrates deeper into the cross section:
  • the calculation model according to the invention dispenses with the application of complex numerical approaches and, on the basis of elementary strength theory and reinforced concrete construction with the aid of linear bar statics, allows proof of the load-bearing safety of load-bearing systems under fire load.
  • the step that is usually missing in the project planning can be In any case, the load capacity calculation can be included with little effort and Measures such as thermal insulation and other constructive measures on their influence be examined. A purely empirical arrangement of such measures can thus omitted. Also, the basic arrangement of thermal insulation in the form of Mats and plastering or protective concrete are offered an alternative, the exclusively based on the principles of reinforced reinforced concrete structures.
