Description

TECHNICAL FIELD

[0002] Steel structure is a main building structure type composed of section steel, steel plate and other materials, and components of the steel structure are usually connected through welding, bolts or rivets. The steel structure has the advantages of light weight and convenient construction, and has been widely used in large workshops, venues and other buildings. In the aspect of fixing the column foot of the steel structure, common methods include exposed fixing and cladding fixing. The former anchors the steel column to the concrete foundation through the bottom plate and bolts, and the latter clads the column foot with concrete and embeds it below the ground. However, the existing fixing methods are mostly rigid connections, and when strong vibration is encountered, the column foot part is prone to irreversible damage due to stress concentration, and the overall structure has limited resistance to high-strength vibration, which is a weak link in the seismic design of steel structures.

[0003] The authorized announcement No. CN219548158U discloses a shock-absorbing spliced steel structure column. The structure cooperates the spring and the damper in the first shock-absorbing assembly to relieve the vibration from above. Meanwhile, the second shock-absorbing assembly is used to cope with the vibration from all around. The column is connected with the fixing seat through bolts, and has certain assembly flexibility. However, the structure still has obvious limitations in practical application. Firstly, the shock-absorbing system is mainly single-stage buffering, and it is difficult to realize multi-stage and progressive energy dissipation and shock absorption, resulting in insufficient shock absorption and support effect.
