Abstract:
This paper depicts the study carried out on comparison of International standards for seismic behavior of a high-rise structure when designed and analysed by three International Seismic Codes namely, Indian, European & New Zealand Codes. The chosen standards are Indian code i.e. IS 1893:2002, Eurocode 8:2004 and New Zealand Code NZS 1170.5 2004. The study helps in understanding the main contributing parameters responsible for poor performance of a high-rise structure during an earthquake, so as to achieve their adequate safe behavior under future earthquakes. The structure analysed and modeled for the study is a G+24 RCC residential structure with a Special Moment Resisting Frame (SMRF). The performance of the building is reviewed by carrying out Response Spectrum Analysis using the software ETABS2015, by implementing the seismic parameters relevant in the Indian, Eurocode and New Zealand standards. The analytical results of the model buildings are then represented graphically and in tabular form, it is compared and analysed taking note of the significant differences. The paper focuses on putting forward the variations in the results obtained by using the three codes i.e. Indian, Eurocode and New Zealand code. A comparative analysis is performed in terms of Base shear, Story Displacement and Story Drifts in X, Y and Z direction Floor wise of different codes.
