Problems solved by technology

Under the action of wind load or earthquake load, there will be a relatively large interstory displacement difference between the infill sub-floor and the main structure, and the key nodes of the suspended steel columns may fail, resulting in a reduction in the seismic performance of the sub-floor, making the sub-floor Safety performance is affected

Abstract

The invention relates to the field of construction engineering, in particular to an assembled energy-dissipating node connected to a suspended steel column and an installation method thereof. The energy dissipation node includes end plates, energy dissipation node webs, and energy dissipation node flanges. The energy dissipation node flanges are arranged opposite to each other, and the energy dissipation node webs are arranged opposite to each other. At the top of both the node webs, the dissipating node webs are located between the opposing dissipating node flanges; the dissipating node webs and the dissipating node flanges are used to hold the suspended steel columns. When wind load or earthquake load occurs, energy-dissipating nodes can consume the energy generated by them, reduce the interstory displacement difference between the infill sub-floor suspended on the suspended steel column and the main structure, and improve the seismic performance of the sub-floor , so that the safety performance of the sub-floor is guaranteed.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to an assembled energy-dissipating node connected to a suspended steel column and an installation method thereof. Background technique [0002] With the continuous development of structural engineering technology, buildings are increasingly developing towards long-span and high-rise buildings. Compared with the traditional steel frame, the suspended structure system is a structural system that can provide greater space requirements. It has a unique architectural shape, superior structural performance, effectively reduces the amount of steel used in the building, and generates huge social and social benefits. Economic Value. [0003] In the suspended structure system, the load of the infill sub-floor is transferred to the top horizontal member of the giant frame column through the suspended steel column and energy-dissipating nodes, and further transmitted to the frame column...
