Embodiment Construction

[0042] combine image 3 - Fig. 12 illustrates that the steel frame self-resetting energy-dissipating embedded column base of this embodiment includes four buckling-constrained energy-dissipating plates 8, eight friction pads 5, an upper column section, a lower column section 7 and a High-strength steel rod 2. The upper column section is located on the upper part of the lower column section 7, the high-strength steel rod 2 is placed inside the upper column section and the lower column section 7, and the buckling restraint energy dissipation plate 8 is fixed at the connection between the upper column section and the lower column section 7. A friction backing plate 5 is set between the buckling restraint energy dissipation plate 8 and the upper column section, and a friction backing plate 5 is also set between the buckling restraint energy dissipation plate 8 and the lower column section 7, and the friction backing plate 5 and the buckling restraint energy dissipation plate 8 The...

Abstract

The invention discloses a post-earthquake self-recovery embedded energy dissipating steel column base. The post-earthquake self-recovery embedded energy dissipating steel column base comprises an upper column section, a lower column section, a buckling-restrained energy dissipating plate and a high-strength steel rod; the upper column section is located on the upper part of the lower column section, the high-strength steel rod is arranged in the upper column section and the lower column section, and the buckling-restrained energy dissipating plate is fixed to the connection of the upper columnsection and the lower column section. The post-earthquake self-recovery embedded energy dissipating steel column base has the advantages that two-way bearing is high, two-way energy consumption is high, two-way post-earthquake self recovery is carried out, the stress is simple and clear, excessive local stress after the column base is pried is avoided, on-site construction is convenient, the usefunction of the building cannot be affected.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a post-earthquake self-restoring embedded energy-dissipating steel column foot. Background technique [0002] my country is one of the countries with frequent earthquakes and the most severe earthquake disasters. The damage and collapse of buildings during earthquakes is the direct cause of economic losses and casualties. For this reason, the traditional anti-seismic technology of structures is mainly anti-collapse design, which uses the plastic deformation of the main structure itself to consume earthquake energy to prevent structural collapse and ensure the safety of people's lives and properties. However, recent earthquake damage shows that although this design concept has achieved the fortification goal of strong earthquake resistance, the main structure has suffered serious plastic damage, and the damaged parts are mainly concentrated in the beam-column joints and column f...
