Problems solved by technology

However, since the working mechanism of this type of damper is mostly pushing, and the high-rise structure mainly undergoes bending and torsion deformation during the earthquake, the displacement change at the end of each damper is not significant, which limits the damping effect

Embodiment

[0033] Example 1: Now refer to figure 1 , which illustrates prior art examples of frame structures used in building structures, ie steel frame structures, or frame sections of steel frame concrete core tubes in tall structures, or frame sections of other structures. When the building is subjected to strong wind or earthquake loads, the beam 11 and the first column 12 and the second column 13 deform, failing to provide meaningful damping.

[0034] exist figure 2 In, an embodiment of the invention described herein, the easily reset replaceable bending energy dissipation connecting device in this embodiment partly replaces figure 1 At the end part of the middle beam 11, because the easily resettable and replaceable anti-bending energy-dissipating connecting device 15 only replaces a section of the beam 11, other space inside the building will not be wasted. In this case, when the building structure is subjected to strong wind or seismic loads, the present invention deforms and...

Abstract

The invention discloses a beam-end connecting device of a novel structure and provides a connecting device capable of resetting easily, replaceable, resistant to bending and capable of dissipating energy. The connecting device is applied to the beam-end portion of a framework beam or a coupling beam in a building structure or a bridge structure, the connecting device is activated when the beam-end generates bending moment to a certain degree, and a damper of the connecting device can remarkably improve the structure damping level. Under the condition that the structure bears general power loads, the beam-end connecting device of the novel structure provides damping, thereby assisting in controlling storey drift, speed and acceleration. Under the condition that the structure bears high-intensity power loads, the connecting device has self-adaptability to a certain degree, after the storey drift angle is larger than a preset critical value, the connecting device can centralizeearthquake damage to a replaceable intensity weakening section of the connecting device, ductility and energy dissipation are provided through buckling deformation of flanges, and the overall stability of the structure is ensured. Besides, the connecting device is replaceable and provided with a rotation reset button, thereby restoring post-earthquakeresidual drift easily, being convenient to replace and effectively reducing all kinds of losses caused after an earthquake.

Description

technical field [0001] The invention relates to the fields of construction engineering and bridge engineering, in particular to a structural system with frame beams and connecting beams. The invention belongs to post-earthquake low-damage, replaceable, multi-material composite beam end connection devices, and also belongs to structural vibration control devices, A type of structural anti-seismic device. It belongs to the technical field of structural engineering. Background technique [0002] In earthquake disasters, the quality of building structures has an important impact on the damage caused by earthquakes, so better seismic design of building structures has always been the goal pursued by structural engineers. The frame structure system is currently the mainstream structure system, because of its advantages of high indoor space utilization rate and high degree of assembly, it has broad development and application prospects in engineering practice. [0003] Since steel...
