Re: Cantilevered Stairs

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I have designed quite a few "cantilevered" stairs but they have always been
in reinforced concrete. All stairs were designed as per British Standard
Codes and were built in UK. Also, the Institution of Structural Engineers
published the design of "cantilevered" staircase in one of their monthly
magazines. I beleive that the theory is the same whether you design in
concrete or structural steel. If you are interested and think that it may
help you, I can fax you copies of my calculations and also reference where
to find the article by The Institute of Structural Engineers in UK. Send me
your fax number at ggci(--nospam--at)cadvision.com or my Fax 403-278-8415. I live in
Calgary, Alberta, Canada and my name is Chandra Gajjar. I run my own
consulting company called Gajjar Group Consulting Inc. Write to me if you
think I can of any help. Regards,

Chandra Gajjar, P.Eng., F.I.Sturct.E.
