Passive Damping Active Damping Semi-Active Damping DAMPING SYSTEMS FOR STRUCTURAL ENERGY DISSIPATIONAli Irmak Ozdagli, Dr. Shirley DykeCollege of Engineering, Purdue University, West Lafayette, IN • The simplest way to introduce damping to a structure • Inexpensive to fabricate • No power requirements • Lack of versatility when dynamics of the structure vary with time • Increased effectiveness of structural damping • Increase in cost due to constant power consumption • Possibility of system failure during an earthquake • More versatile compared to passive damping • More affordable in terms of energy consumption compared to active damping • Complex algorithms to adapt the system Power Signal Control Signal Sensor Signal Accelerometer
