Earthquake is a compartment of structural analysis which involves the computation of the response of a structure subjected to earthquake excitation. This is required for carrying out the structural design, structural assessment and retrofitting of the structures in the regions where earthquakes are prevalent. Fast urbanization has led to construction of a large number of multistoried buildings. Buildings Safety from seismic point of view is important. Now a day’s number of tall buildings are going on increasing which are quite flexible and having very low damping value to minimize increasing space problems in urban areas. Base isolation techniques are quite effective. It requires insertion at foundation level which required constant maintenance. Active control techniques turn out to be costly as it requires continuous power supply. These structures should be designed to oppose dynamic forces through a combination of strength, flexibility and energy absorption such that it may deform beyond elastic limit when subjected to severe earthquake motion. To make these structures free from earthquake and wind induced structural vibration, various techniques has been adopted which can be broadly classified into 4 categories. (i) Active control, (ii) Passive control, (iii) Semi-active control and (iv) Hybrid control. The Soft storey will be made up of concrete and its columns, beams , slabs sizes will be smaller than other storey of the building. TMD being made of concrete will have the same damping ratio as that of main building. For square columns TMD can be consider for square buildings.
