Analysis on Seismic Induced Vibration Control by Dampers in Tall Buildings Using ETABS Software

The Need for taller structure in construction and real estate industry is on a tremendous increase over the world. Vibration creates problem to serviceability requirement of the structure and also reduces structural integrity with possibilities of failure. Current trends use several techniques to reduce earthquake induced structural vibration. This thesis presents comprehensive researches on earthquake-induced vibration control technologies that are applied to high-rise structures; Damper is widely used to control structural vibration under earthquake load. First, earthquake effect on high-rise structures is analyzed, and earthquake-induced responses of high-rise structures are analyze. second, optimal parameters of damper installed on structures are deduced, which carefully consider the interactions between the main structure and the damping system, The efficiency of the passive control system is evaluated by the performance of the building will be studied considering building with damper and without damper by using ETABS Software. to find out the seismic response (storey drift, storey displacement, story stiffness and story force) of building with and without any damping device. This thesis work different model with different shape of structure, different locations of damper and different height of structure of building have been modeled. Under this work first of all, the structure has been done without any damping device and secondly the same building with different shape of structure, different locations of damper and different height of structure. These are the result obtained from ETABS Software by comparing the values with and without damper.
