RCC beam depth
Dear all
One of my colleague IIT qualified M tech 60 years old having 35 years experience in designing working in UAE for the calculation for a tender estimation for an Industrial project, assuming the depth of proposed beam to be span/10 for UDL 6 to 8 tonne/metre. The building is RCC framed structure. Concrete grade 40
Span / 10  estimation is OK or no. I think no. What about u all pl
Regards
Suraj

Dear Mr. Suraj,

I do not see anything wrong with span / 10 for depth of beam for
working load of 60kN to 80 kN / meter. I presume you are not
thinking of beam 20 to 30 meter span !!!
Actually effective depth can be span / 10 to span / 20 for span
up to 10 meters for deflection control, but it will
all finally depend upon Limit moment and corresponding Ku which
normally should not exceed 7.5

Hope this clarifies your query.

dear suraj,
isnt he expected to work out a few designs and check the sizes...if not on a
computer then  manually...my dear friend designing shdnt be treated so
casually and even estimating ...its better he designs a few main beam
sections and confirms sizes bef estimating

Dear Suraj Singh Ji

Nothing is wrong in design,as long as it works, previously (at the time he did his BE ) steel used to be round bars, cement was not that good, and people used to remain safe, in old building still you will see heavy beams and columns now a days it is dieting era every one longs to be thin and slim so are the RCC frames. both of you are right at your own place, as far as design and estimation is concerned it all depends on situations and differs from work to work had it been a common case then IEI must not have started PE registration.
