Title:
CORE ENERGY CONSUMING STRUCTURE CAPABLE OF BEING PARTIALLY FUSED FOR DUAL-ORDER ENERGY CONSUMPTION, AND AXIAL STEEL DAMPER
Document Type and Number:
WIPO Patent Application WO/2023/125066
Kind Code:
A1
Abstract:
The present invention relates to a core energy consuming structure capable of being partially fused for dual-order energy consumption, and an axial steel damper. The axial steel damper comprises the core energy consuming structure and a peripheral constraint member, the core energy consuming structure at least comprises an austenitic structure steel plate and a ferrite structure steel plate, and the austenitic structure steel plate and the ferrite structure steel plate are connected without constraint. A microstructure of the austenitic structure steel plate is mainly metastable austenite, and a microstructure of the ferrite structure steel plate is mainly ferrite; and the austenitic structure steel plate has yield strength not less than 220 MPa and an elongation not less than 40%, and the ferrite structure steel plate has yield strength less than 180 MPa and an elongation not less than 30%. The axial steel damper in the present invention has characteristics of small yield displacement, excellent ductility and cumulative plastic deformation performance, being able to achieve partial fusion of the core energy consuming structure so as to limit output of the damper, and being able to fail with the same redundancy as a building main structure.
