Abstract: Seismic resistant deign is a matter of interest for structural engineers these days hence becoming popular in the field of structural engineering. Since there are a number of earth quakes were faced in the society, there is a very much need of this subject to emerge. Many government and some private building owners today require that new buildings be designed to resist the effects of Earthquakes and other incidents that could cause tremendous local damage. In this discussion it may be possible to design buildings to resist such attacks without severe damage, the loading effects associated with these hazards and so intense that design measures necessary to provide such performance would result in both unacceptably high costs as well as impose unacceptable limitations on architectural design of such buildings. Response spectrum is one of the useful tools of earthquake engineering for analyzing the performance of structures especially in earthquakes, since many systems behave as single degree of freedom systems. Thus, if you can find out the natural frequency of the structure, then the peak response of the building can be estimated by reading the value from the ground response spectrum for the appropriate frequency. In most building codes in seismic regions, this value forms the basis for calculating the forces that a structure must be designed to resist (seismic analysis). A response spectrum is a plot of the maximum response amplitude (displacement, velocity or acceleration) versus time period of many linear single degree of freedom oscillators to a give component ground motion. For this purpose response spectrum case of analysis have been performed according to IS 1893. In the Present Study Analysis is carried out for the proposed plan of G+17 building in both Response spectrum and Time history analysis considering Zone-III for Response Spectrum and Bhuj Earthquake 2001 (Gujarat) data gathered from Virtual Data Centre for Time History Analysis and the Results are compared between Response Spectrum and Time history cases which compares Theoretical and Practical data of same zone.
