Description

Support energy dissipation structure

The present invention relates to a supporting energy-dissipating structure, and in particular to a supporting energy-dissipating structure including inter-column elements.

Generally speaking, adding energy dissipation devices to the building structure can absorb part of the earthquake force, making the main structure less susceptible to damage, reducing the shaking of the building, and increasing the comfort of residents.

For example, seismic walls can be used to install steel plates containing viscoelastic materials between the upper and lower structures of the building to absorb part of the seismic energy and slow down the shaking of the building. However, for external forces that affect the building, such as earthquakes, wind shaking, etc., they will have different directional forces, but most seismic walls only provide stiffness and energy dissipation capabilities in a single direction. If it is necessary to overcome multi-directional inter-story displacement, it may be necessary to configure multiple vibration damping walls in different directions, but this makes them occupy a larger space and increase the construction cost.

The present invention provides a supporting energy-dissipating structure, which includes inter-column elements to reduce structural response under seismic force or wind force.

In an embodiment of the present invention, the above-mentioned at least one column element further includes a lead core, and the lead core is covered by an elastic part.

In one embodiment of the present invention, the above-mentioned supporting energy-dissipating structure further includes a plurality of fixing members for fixing two ends of at least one column element to the first member and the second member respectively.

In an embodiment of the present invention, the above-mentioned at least one column element is a circular column or a square column.

In an embodiment of the present invention, the width of at least one pillar element in a horizontal direction is greater than the height of at least one pillar element in a vertical direction.

In an embodiment of the present invention, the width of at least one column element in a horizontal direction is smaller than the height of at least one column element in a vertical direction.

Based on the above, in the support energy dissipation structure of the present invention, the inter-column element includes a plurality of elastic parts stacked along the axial direction, and the elastic parts absorb part of the energy of the earthquake force or wind force to slow down the shaking of the building.
