Structural Analysis and Design of a 30-Story Tower with Friction Dampers

In the last few decades the wide of usage of the deformable system or dampers increase significantly. Dampers are the elements that reduce the vibration of the lateral load which are caused by earthquake or wind. Dampers play the vital role todecrease the absorption of the lateral load.[1] this paper have compered the results of technical and economical of the 30-story steel structure with two options including, special moment frames (SMF) plus friction dampers, and special moment frames without using of dampers. This two structure classified with 26-story above the ground and 4-storyunderground. Shear walls have been implemented its 4-story of basemen. In addition, soil behind the shear walls has been compacted.
