CORE ENERGY DISSIPATION STRUCTURE AND AXIAL STEEL DAMPER

WIPO Patent Application WO/2023/125063

A1

The present invention relates to a core energy dissipation structure and an axial steel damper. The axial steel damper comprises a core energy dissipation structure and a peripheral restraint member. The core energy dissipation structure at least comprises an austenite structure steel plate and a ferrite structure steel plate; the ferrite structural steel plate is necessarily and only adjacent to the austenite structure steel plate, and is connected to the austenite structure steel plate by means of welding. The microstructure of the austenite structure steel plate is primarily metastable austenite, and when the austenite structure steel plate is subjected to periodic alternating stretching-compression plastic deformation, a reversible phase change between austenite and strain-induced ε martensite occurs in the austenite structure steel plate. The ratio of the maximum allowable displacement to the yield displacement of the axial steel damper of the present invention is not less than 10, and the maximum allowable displacement is not less than 1/60 of the length of the axial steel damper. The axial steel damper is able to complete at least 30 cycles of periodic alternating stretching-compression plastic deformation under the maximum allowable displacement.
