The width of an RCC beam is limited to -

[Dnyan Deshmukh]

The width of an RCC beam is limited to -

(a) L / 60

(b) 100 mm + L / 100

(c) 200 mm + L / 200

(d) No such limit.


where L = span.

The correct Answer Is
(a) L / 60

 

[K deka]

I think its (a) L/60.
I m not sure.. i also want to know the correct answer.

 

[Sathish vip]

option A).L/60 i think pls let us know the correct answer as it would be helpful for emerging engineers

 

[Jayant Joshi]

Do not know.

But I believe there is no such limit.
Normally all beams are resting on columns and the width of beam should not be more then the width of columns, this is the governing criteria.

If the answer is some thing different, please share so we can learn.

The width of an RCC beam is limited to -

(a) L / 60

(b) 100 mm + L / 100

(c) 200 mm + L / 200

(d) No such limit.


where L = span.

In general, the ratio of overall width (b) to depth (D) in rectangular RCC beam sections is in the range of 1.5 to 2.
The ratio of effective length to effective depth of the member governs the span of beam.
IS 456: 2000 prescribed a limiting value of 'l/d'=7, for cantilever beams for spans up to 10m. So, if we go beyond a certain length, we will end up with large depths as per the relation: d=l/7.
