Seismic Performance Evaluation of Steel Moment Resisting Frames Equipped with Tuned Liquid Damper

A common approach to mitigate the structures` response under dynamic loading is to attach a dynamicvibration absorber such as Tuned Liquid Damper (TLD) to the structure. A TLD is a passive controlsystem, which reduces the structures` response utilizing the fluid sloshing motion to dissipate the lateralexcitation energy. For rehabilitation of existing intermediate steel moment resisting frames in thisstudy, the TLD is modelled as an equivalent Tuned Mass Damper that Yu developed. This paper aimsat investigating the efficiency of TLD in improving seismic performance of existing intermediate steelmoment resisting frames based on nonlinear dynamic analysis.
