    Recommendations provided by seismic codes help the designer to improve the behaviour of structures so that they may withstand the earthquake effects without significant loss. Seismic codes are unique to a particular region or Country. They take into the account the local seismology, accepted level of seismic risk, properties of available materials, methods used in the field of earthquake engineering and property. Most of the recommendations of IS codes are based on observations during past earthquakes as well as experimental and analytical studies made by scientists, engineers and seismologists. In India, the 1st seismic code namely IS 1893 was published in 1962. Seismic analysis and design for this project will be in compliance with IS 456/IS 1893, The concept of earthquake resistant design is that the building should be designed to resist the forces which arises due to design basis earthquakes, with only minor damages and the forces, which arises due to maximum considered earthquakes with some accepted structural damages but no collapse. The design philosophy was established considering the following aspects: The structure should withstand the moderate earthquakes, which may be expected to occur during the service life of structure with damage within acceptable limits. Such earthquakes are characterized as design basis earthquakes. The structure should not collapse when subjected to severe ground motion that could possibly occur at the field. Such earthquake is characterized as maximum considered earthquakes. Buildings are designed as per Design based earthquake, but the actual forces acting on the structure is more than the design earthquake. So, in higher seismic zones Ductility based design approach is preferred as ductility of the structure narrows the gap. The primary objective in designing an earthquake resistant structure is to ensure that the building has enough ductility to withstand the earthquake load.
