Dear All,

Someone has misquoted me as follows:

" If we follow Shri. Jaiswal's remarks, IS codes for built up sections (not
CFSS!) do not allow us to go for lesser thickness whereas the manufacturers
recommend it (albeit after extensive experimental data). Hence, his advise
to be careful if you need to follow IS!!!"

I never meant it. I meant other way!!

In fact I am of the opinion one should not blindly follow a foreign code. In
case of MBMA which is not even a code but only industry recommendation from
a particular interested body promoting the particular product. One may agree
or may not it is certainly individual decision (which is also relative to
the awareness one has in the particular field). But PEB manufacturers
projecting that it is a standard is not true!

I was only trying to point that I, as designer had put my basic durability
criteria as per IS to have base metal thickness not less than 6mm for main
members and 2.5mm for secondary members like purlins. Whereas PEB
manufacturers were promoting thickness as low as as 4mm for main members!!

This may also not be acceptable criteria to most of designers abroad that is
another point but what is more alarming that sales talk of  having supplied
so many buildings in gulf / USA with the same specifications etc, without
any proof of actual specs followed in project!!

As structural designers we have to use proper judgement.

With warm regards.

Arvind
