Description

technical field [0001] The invention belongs to the technical field of connecting beams, in particular to an energy-dissipating connecting beam. Background technique [0002] The energy-dissipating and shock-absorbing structure consumes the input energy of the earthquake by arranging energy-dissipating components at appropriate positions, thereby increasing the structural damping and reducing the seismic response of the structure, which can protect the safety of the main structure. Generally, energy-dissipating coupling beams are used to The main structure is treated with energy dissipation. Traditional energy-dissipating coupling beams can only meet the seismic performance requirements by improving the strength, stiffness and ductility of the structure. This method not only seriously affects the economical efficiency of the structure, but also makes it difficult to significantly improve its seismic performance. [0003] The existing coupling beams have poor energy dissipat...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an energy dissipation connecting beam. By designing the cross-section of the first support plate as an I-shaped structure, and setting a number of second fixing plates between the two plates of the first support plate, the fourth A set of first damping pads is fixed on the fixed plate, and a second damping plate is fixed on the fifth fixed plate, which solves the problem that the existing coupling beams have poor energy dissipation effect during use, especially in strong external environments. Under the interference of the coupling beam, the energy from the impact cannot be reduced in time, which will cause certain damage to the object protected by the coupling beam and affect the normal use of the object.
