EFFECT OF TUNE MASS DAMPER (TMD) ON HIGHRISE BUILDING SUBJECTEDTO LATERAL LOADS

Strong earthquakes have occurred in many countries and have caused many problems including casualties, economic loss, destruction of infrastructures, and even leaking of radioactive materials. Therefore, earthquake resistant design and reinforcement of existing structures have become increasingly more important due to increasing probability of strong earthquakes. Especially, a higher level of earthquake resistance is required for infrastructures and industrial facilities as it has been shown in historical earthquake studies. In the field of the structural; engineering the major aspect of analysis and designing the building is to ensure the structural stability against effect of various forces especially lateral forces, earthquake and wind are the two important external forces that must be taken in to considerations while designing a building as they play a major role in effecting the stability of structure. The main principle of designing the structure under seismic is to reduce the seismic force or seismic risk. Due to rapid urbanization and growth in industrial sector which led to the increase in the multistory structures construction. Efforts are being taken to reduce or control the seismic response due to wind and earthquake loading (lateral loading) which resulted in developing of seismic control devices such as active control devices and passive control devices. Several seismic resistance techniques are available, depending on the various types and conditions of structures. In this project a symmetrical building of 20 stories with and without dampers (TMD) in zone II and zone V with medium soil is modelled and analyzed in ETABS 2015 under seismic zone II and V and the change in structural response in this is studied
