Embodiment Construction

[0074] In the following elaboration, the first involves Figure 1 to Figure 10 .

[0075] exist figure 1 The load-bearing structure 1 for absorbing the force F(t) acting at the upper end is shown in the undeformed state (F(t)=0). The load-bearing elements 2 of the load-bearing structure 1 consist of rods and beams. The cavity 5 is located in the carrier element 2 which is designed as a steel tube. The axis of the center of gravity of the support structure 1 is indicated with 9 and the axis of the center of gravity of the support element 2 is indicated with 8 . The foundation 16 serves as an abutment 21 for the load-bearing structure. figure 2 A section through carrier element 2 with cavity 5 is shown.

[0076] exist image 3 shown in the figure 1 Section of the load-carrying structure 1 with the rod 4 installed and the remaining volume of the cavity 5 filled with the material 6 . The rod 4 is fastened immovably at the abutment 21 by means of the anchor 3 . For a bett...

Abstract

In a load-bearing construction (1) having at least one load-bearing element (2), the load-bearing element (2) has at least one cavity (5) in which at least one rod (4) is disposed, the total cross-sectional area of all rods (4) each arranged in a cavity (5) being smaller than the cross-sectional area of this cavity (5), and the remaining volume of the cavity (5) being filled with a material (6). The rod (4) is displaceable along its length relative to the load-bearing element (2) when the load-bearing element (2) is deformed, the rod (4) being non-displaceably fixed at only one point relative to the load-bearing element (2) and being designed such that it dissipates energy upon the occurrence of a relative displacement with respect to the load-bearing element (2).

Description

technical field [0001] The invention relates to a carrier structure with at least one carrier element according to the preamble of claim 1 . Background technique [0002] The load-bearing structure can be, for example, a tall building, a chimney, a tower or a bridge. [0003] The load-bearing structure is formed, for example, from rods, beams, sheets or plates. A load-bearing structure in the field of construction technology has at least one support. Supports (lagers) or foundation structures (fundierungskonstruktion) can be used as supports. [0004] In load-bearing structures, vibrations can be excited by dynamic actions (earthquakes, wind, pedestrians on bridges, etc.). There are different methods to reduce vibrations. [0005] ●Change the frequency position (Frequenzlage) [0006] In order to reduce the vibrations, a natural frequency offset is provided as a countermeasure so that the distance from the excitation frequency (Erregerfrequenz) is as large as possible. ...
