Indian Concrete JournalSummary: The paper presents how Extended Three dimensional Analysis of Building Systems (ETABS) software and Structural Analysis and Design Professional (STAAD Pro) each give steel reinforcement quantities against the provision of section 26.5 of Indian Standard (IS) 456:2000. It is factual that manually performing seismic analysis can be very tedious, timeconsuming and uncompetitive in an industry that is competition driven. In addition, the tendency of making errors due to the transposition of figures is high. Therefore, the need to adopt the computer and its program in the analysis and design of buildings and structures is overdue. However, it should not be at the expense of sustainability. The results of seismic analysis and design of a six storey (Ground floor plus five other floors referred to in this paper as G+5) building in ETABS software and STAAD Pro are used to examine how they both satisfy important provisions set out in the Indian Standard. Manual calculations were also done by following the provisions set out in IS 456:2000 and IS 1893 (Part I): 2016. The results shows ETABS gives much steel reinforcement in its output by 0.58% compared to STAAD Pro and 0.02% more than manually calculated result. In addition, the storey displacement, storey drift, base shear, moments and shear forces showed that there was an only marginal difference in the results from the ETABS and STAAD Pro analysis. ETABS analysis produced the highest values with a maximum difference of about 7% higher than results from the STAAD Pro analysis.

The paper presents how Extended Three dimensional Analysis of Building Systems (ETABS) software and Structural Analysis and Design Professional (STAAD Pro) each give steel reinforcement quantities against the provision of section 26.5 of Indian Standard (IS) 456:2000. It is factual that manually performing seismic analysis can be very tedious, timeconsuming and uncompetitive in an industry that is competition driven. In addition, the tendency of making errors due to the transposition of figures is high. Therefore, the need to adopt the computer and its program in the analysis and design of buildings and structures is overdue. However, it should not be at the expense of sustainability. The results of seismic analysis and design of a six storey (Ground floor plus five other floors referred to in this paper as G+5) building in ETABS software and STAAD Pro are used to examine how they both satisfy important provisions set out in the Indian Standard. Manual calculations were also done by following the provisions set out in IS 456:2000 and IS 1893 (Part I): 2016. The results shows ETABS gives much steel reinforcement in its output by 0.58% compared to STAAD Pro and 0.02% more than manually calculated result.
