Abstract
I.S. 1893 : 2016 (Part 1) (Sixth Revision) was adopted by Bureau Of Indian Standards in December 2016. The definition of Soft Storey condition has been altered and equal or higher lateral stiffness of lower storey as compared to immediate upper storey is proposed than that were allowed in I.S. 1893 Part 1 : 2002. Due to scarcity of land, development rules regarding open spaces and parking, multistorey and high-rise structures are constructed with transfer girders to create column free spaces to provide clear drive way and parking movability. The present analytical study concentrates on effect of variation in stiffness of transfer girder on the lateral stiffness of the frame floated from it under lateral load. This Analytical study of R.C. frame on R.C. transfer girder is done using Staad Pro Software. The results show that, the soft storey condition of a floating frame remains unaltered, irrespective of the change in stiffness
or end support conditions of the transfer girders or its placement on transfer girder
