  1. Seismic Control Applications in Taiwan Jenn-Shin Hwang National Taiwan University of Science & Technology National Center for Research on Earthquake Engineering JSH@mail.ntust.edu.tw , jshwang@ncree.gov.tw

  2. Equationof Motion Energy Equation

  3. Energy Demand by Earthquake Energy Supply of Structure Earthquake Input Energy Viscous Damping Energy Hysteretic Energy Kinetic Energy Elastic Strain Energy Absolute Energy Equation of A Structure Responding to An Earthquake

  4. Conventional Seismic Design Inelastic deformations of structures Energy Consideration Energy dissipation relies on Damage

  5. Strategies for Seismic Protection of Structures (1) Increase Energy Dissipation Capacity of Structures ---- Implementation of Energy Dissipation Devices (2) Reduce Energy Demand by Earthquake ---- Adoption of Seismic Isolation Design

  6. Energy Dissipation Devices Applied In Taiwan • Hysteresis Type Dampers: (Hysteretic Energy) • ADAS (Added Damping and Stiffness) • TADAS (Triangular ADAS) • RADAS (Reinforced ADAS) • LYSSP (Low Yield Steel Shear Panel) • (2) Velocity-Dependent Damper: (Viscous Damping Energy) • Visco-Elastic Dampers, Viscous Dampers • (3) Improved Energy Dissipation Design: (Hysteretic Energy) • BRB (Buckling Restrained Braces or Unbonded Braces)
