Definitions

  • the invention relates to a support structure with at least one support element, according to the preamble of claim 1.
  • the support structure may be, for example, a skyscraper, a chimney, a tower or a bridge.
  • a supporting structure consists of supporting elements, e.g. Rods, beams, discs or plates.
  • a supporting structure in the field of civil engineering has at least one support. Bearings or foundation structures can serve as supports.
  • vibrations can be excited by dynamic effects (earthquakes, wind, pedestrians on bridges, etc.).
  • dynamic effects earthquakes, wind, pedestrians on bridges, etc.
  • a countermeasure is a shift in the natural frequency, so that the distance to the exciter frequency becomes as great as possible.
  • a vibration damper is understood to be an additional mass coupled to the supporting structure by means of a spring and a damping element.
  • Tilger Under a Tilger is understood to be coupled to the support structure by means of a spring additional mass.
  • the amount of damping has a decisive influence on the vibration reduction in the resonance range. It is used between damping in the building material, damping in Components and fasteners and the damping by storage and subsoil differentiated.
  • the change in frequency position is an excellent method for reducing vibrations when the excitation frequency is known, e.g. at a given frequency from the operation of a machine.
  • the excitation frequency is known, e.g. at a given frequency from the operation of a machine.
  • the vibration isolation requires a high additional effort to isolate the structure and to accommodate the e.g. in a vibration-isolated structure occurring during an earthquake large horizontal displacements.
  • Vibration dampers and absorbers are structures that cause high installation and maintenance costs.
  • Increasing the structure damping is a suitable method for reducing the vibration of support structures in the resonance region and for energy dissipation, e.g. during an earthquake.
  • the energy supplied by the earthquake causes the supporting structure to vibrate.
  • a failure of the support structure can be prevented if an effective energy absorption takes place by dissipation of the supplied energy in as many places and at the same time the removal of the vertical load (dead weight and payloads) is ensured.
  • diagonal bars can be connected eccentrically to the beam.
  • flow joints form in the beams in which energy is dissipated by cyclic - plastic deformations.
  • the support structure comprises at least one support element with at least one cavity and at least one bar communicating with the cavity.
  • the cavity is filled with a fabric, the rod being displaceable relative to the support element along its longitudinal extent when the support element is deformed, the rod being immovably fixed at at least one location with respect to the support element and adapted to occur upon occurrence from relative displacement to the supporting element energy dissipates.
  • dissipating is meant the transition from an energy form to heat.
  • the support element has at least one cavity in which at least one rod is arranged.
  • the total cross-sectional area of each arranged in a cavity bars is smaller than the cross-sectional area of this cavity and the remaining volume of the cavity is filled with a ver stuff.
  • the rod is displaceable along its longitudinal extent relative to the support element when the support element is deformed. By this configuration, a high energy dissipation can be achieved.
  • the rod fixed immovably at only one point with respect to the support member and designed so that it dissipates energy when relative shift occurs to the support element.
  • the rod is tubular and defines in its interior the cavity in which the substance is received, wherein the substance is formed as a liquid, wherein the rod when deforming the support member changes the volume of the cavity, causing a shift between the fabric and the rod.
  • a "rod” is defined in the structural analysis so that it can absorb only tensile and compressive forces.A bending rod can of course also occur in a rod, but these are of a much smaller magnitude compared to a beam
  • the invention contemplates steel bars of circular or rectangular cross-section, tension wire strands, steel cables that have considerable rigidity, steel (round or polygonal) hollow sections, and fiber composite bars and strands and wires.
  • Bonding stresses for example due to friction or through the material in the cavity, can be transmitted between the rod surface and the supporting element. Cycling through composite voltage relative shift relationships provides the opportunity to dissipate energy. Depending on the design of the rod and the bond stresses generated by relative displacements, energy is dissipated along the rod. Rods made of a metallic material or a fiber composite material are recommended for good dissipation.

  • water with a kinematic viscosity of 10 ⁇ 6 [m 2 / s] at room temperature or hydraulic oil with a kinematic viscosity of 10 ⁇ 2 [m 2 / s] at room temperature can be used.
  • a preferred filling medium for damping elements is silicone oil.
  • Silicone oils are manufactured for a wider range of applications with kinematic viscosities from 10 ⁇ 6 [m 2 / s] to 1 [m 2 / s]. Of particular importance are methyl silicone oils.

The melting point is -50 0 C, the flash point at 250 0 C and the ignition temperature at about 400 0 C. The density is about 970 kg / m 3
  • Methyl silicone oils have a large viscosity range and low viscosity dependence on temperature. Another feature is the high compressibility. As a result, even with very high compressive stress there is no danger of the silicone oil getting stuck.

  • a good damping of vibrations in a support structure according to the invention is achieved if the dimensions of the support structure along its gravity axis are at least ten times greater than in the orthogonal to the gravity axis arranged cross sections and when a support element is arranged approximately parallel and at a distance from the axis of gravity of the support structure.
