Variable Width Steel Slit Damper (HI Damping Damper) Seismic Reinforcement Method

A damper composed of struts with varying widths, efficiently absorbing energy from earthquakes to enhance the seismic performance of structures.

Method Overview

Damping Damper Features

Item Details
Outstanding Energy Dissipation In a truss type, adjusting the width, thickness, and angle of side and middle streams enables control of sudden displacements during earthquakes: Ensuring stable hysteresis behavior and maximum deformation capacity.
Optimal Cost Efficiency Minimizing installation space and building damage
Applying performance-based seismic design for cost reduction
Wide Applicability
Various types suitable for building layouts and characteristics: applicable both internally and externally Ease of On-Site Installation
Factory-preassembled dampers with dry installation: enabling convenient construction Excellent Durability
No need for discontinuous welding or joints: preventing cracks during plastic deformation Simple Maintenance
Damaged dampers can be individually replaced after earthquakes: easy maintenance Testing and Verification Process
Tests and verification via KOLAS-certified institutions Damper Cost Efficiency

Damper Cost Efficiency

Reduces seismic loads by 25%, saving over 5% of frame construction costs
and shortening construction time by more than 5% in new housing projects
In remodeling (major repairs and partial extensions), applying dampers can
cut construction costs by over 50%, shorten construction periods by over 50%, and minimize interior work.
A method that enables seismic reinforcement even while existing shops remain open.
