ANALYSIS OF G+15 NORMAL RCC FRAME AND ZIPPER BRACED FRAME BY PUSH OVER METHOD IN SAP2000

Abstract

This paper describes the comparative analysed results of R.C.C zipper braced frame with standard RCC regular frame for residential building of G+15 storey. The modelling of zipper braced frame were done by using pushover analysis method in SAP2000 software. Pushover analysis were performed for estimating the hinges in both frames, displacement, base shear and modal time period. The analysis indicates that there is almost insignificant hinges in zipper braced frame when compared with the normal frame of R.C.C. As well Zipper braced frames shows less time period about oscillation as compared to normal frame. The ATC capacity spectrum method evaluated the capacity curve which shows if more displacement than more will be the base force, in which maximum displacement and base force is in normal frame and zipper proves to be in safer zone.
