AI Technical Summary

Technical Problem

Existing multi-level seismic dampers have low graded triggering accuracy, poor structural stability, and insufficient multi-dimensional adaptability, making it impossible to achieve stable gradient damping.

Method used

A graded limiting sleeve assembly consisting of a first sleeve, a second sleeve, and a third sleeve nested coaxially from the inside out is used. Combined with the sliding cooperation of the limiting groove and the limiting block, the starting threshold of each level of the shock absorption component is precisely controlled to ensure that the sleeve slides only along the axial direction and avoids circumferential rotation.

Benefits of technology

It achieves gradient damping for minor, moderate and major earthquakes, with precise and stable graded response, avoiding the problems of ambiguity, premature or delayed triggering and failure of traditional dampers, and improving energy consumption efficiency and structural safety.
