Alternative Solution of TMD adapted Tower with Composite Steel Deck Slabs; Advantages : Major decrease in the tower total mass. Seismic shear forces reduction. Seismic base moment reduction. Economy for foundation & pile design Decrease in the period of the building due to the dead mass decrease. This causes increase of the tower’s frequency. Required damper mass will be less than compared to PT RC slab design. Total weight and the total cost of the damper will be less compared to required damper for initial PT RC slab design.
