Study Of Effect Of Different Types Of Dampers In Design Of High Rise Building For Dynamics Loads

Abstract

Structural control is one area of current Research that looks promising in attaining reduce structural vibrations during loading such as earthquakes and strong winds. There are three primary classes of supplemental damping devices, categorized into three corresponding control strategies. The first class of supplemental damping devices is passive. Passive devices are non-controllable and require no power. The second class of supplemental damping devices is active. Active devices are controllable, but, require significant power to operate. The third class of supplemental damping devices is semi active. Semi active devices combine the positive aspects of passive and active control devices in that they are controllable but require little power to operate. In seismic structures upgrading, one of the lateral force reduction caused by the earthquake is use of dampers. During an earthquake, high energy is applied to the structure. This energy is applied in two types of kinetic and potential to structure and it is absorbed or amortized. If structure is free of damping, its vibration will be continuously, but due to the material damping, vibration is reduced. on the seismic performance of building structural systems having passive damping devices installed within frame. The study of the main objective to check performance of building when designed as per Indian Standard. The building will be analyze is G+25 R.C framed building of symmetrical rectangular plan configuration for zone IV. Response Spectrum Method of seismic analysis will be used. The paper gives the study of different literature investigation taken on effect of different types of dampers in design of high rise building for dynamics loads.
