Abstract
In the present study, a multi-storey 3-D RC frame with core wall at the centre is considered for finding out the shortening of column. The parameters considered for the study are story height of the RC frame and effects of outriggers under the action of elastic, creep and shrinkage shortening. The story height is varied from 20 story to 100 story and the differential shortening is found to be increasing linearly along with height. Also outriggers are introduced in the RC frame at different levels and it was found that the differential column shortening is reduced by 45% for 60 story and 50% for 80 story frame. The present analysis is carried out using a finite element software MidasGen and by plotting storey height versus differential column shortening between the outer peripheral column and the core wall for various story heights with and without outriggers
