A new concept of a “lower-bound transfer function (LBTF)” and frequency-domain optimal damper design method are presented. LBTF expresses an ideal performance for response control in the frequency domain under constant sum added damping coefficients (or total cost dampers). The effectiveness each mode can be captured visually through plotting amplitudes model LBTF. An efficient generation LBTFs...

This study focuses on the modeling of manufactured damper when used in steel buildings. The main aim dampers is to protect buildings from damaging effects that may result due earthquakes by introducing an extra damping addition traditional damping.Only Pure Manufactured Dampers, has been considered this study. Viscous generally preferred structural engineering as it leads a linear model then du...
