I need your kind help on the following.
As per clauseno 7.3.3 of older version of part 1 of IS 1893 i.e. IS 1893-1-2002, loadcombination 1.2(DL+IL+EL) changes to 1.2DL+0.6IL+1.2 EL for IL more than 3kPa and1.2DL+0.3IL+1.2EL for IL as 3kPa or less with provision that floor LL shall notbe reduced as per part 2 of IS 875. Iíve studied in one of the code reviewdocuments by Prof. Shri SK Jain that this clause of code should be removed. In thenew code (2016 version) it is mentioned that (section 7.3.3) where IL is notassessed as per sections 7.3.1 and 7.3.2 of the code only that part of IL whichpossesses mass shall be considered andÖ.<o></o>
The new codeclause is not clear to me, but it appears to me that we can no longer usecombination 1.2DL+0.6IL+1.2EL as it is not mentioned. This is my humblerequest to the SEFIans to confirm whether this load combination may be usedbased on the latest code.<o></o>
