COST ANALYSIS OF RCC BUILDING SUBJECTED TO DIFFERENT CROSSSECTION OF COLUMN IN SEISMIC ZONE IV

Abstract

This paper presents the cost analysis of low-rise building and medium-rise building havingdifferent cross-sectionof column i.e. rectangle, square & circular. In order to perform this study, different models were prepared (G+3, G+7, G+11 storey buildings)and each model was analyzed and designeddesigning software(Staad.pro)for different variable loads by Response spectrum method(dynamic seismic analysis in zone-IVas per IS: 1893-2016). Cross-sectional area, percentage of steel and total quantities of concrete and steel were recorded from staad.pro and then cost analysis was performed by considering the rates of concrete and steel.The results of the analysis show that the total cost of G+3 building (i.e. total cost of concrete and steel) is minimum for the building having rectangle cross-section and found safe and economical, the total cost of G+7 building (i.e. total cost of concrete and steel) is minimum for the building having square cross-section and found safe and economical and the total cost of G+11 building (i.e. total cost of concrete and steel) is minimum for the building having square cross-section and found safe and economical.
