Investigation the Effects of Multiple Tuned Mass Damper on Reduction of Seismic Parameters of Tall Buildings Regular and Irregular on Plan in Steel Flexible Structures Under Near and Far-Fault Earthquakes

The tuned mass damper is one of the latest structural control system that helps the structure to damp the dynamics loads. So far using the Tuned Mass Damper (TMD) on the roof or a few dampers was installed at several points at the height of the building or other levels of the building was popular, b...
