Dear All,

I would like to highlight the impact of the revision to IS:800 as per the
draft that is in circulation, with respect to the other codes which are not
being revised, specially the following

**806-1968 Code of practice for use of steel tubes in general building
construction (first revision)
**4000-1992 Code of practice for high strength bolts in steel structures
(first revision)
**4923-1997 Hollow mild steel sections for structural use (second revision)
**11384-1985 Code of practice for composite construction in structural steel
and concrete.

My concerns are as follows

1) How do we deal with the incompatibility generated by using LSM (Limit
State Method) in the revised IS:800 and the WSM (Working Stress Method)
still in force in the other codes.

2) Since there are a lot of references to hollow sections in the draft
revisions (unlike the earlier 1984 version), what would be the criteria for
decisions, in case of conflicting guidlines with IS: 806 & IS:4923. This
issue is particularly relevant as the popularity of hollow sections is on
the rise.

I hope to be this forum will be able to throw some light on these concerns

Regards

Pankaj
