### What is the reinforcement for 12m span beam? - Quora

I also think that there is no limitation for the length of a beam unless some factors are presumed. Let me explain this by a simple beam case. [Notation] L : length of beam b: width of beam h: depth of beam y: half depth of beam I: inertia moment ...sp.info DEFLECTION ANALYSIS OF A 12 METRE CONCRETE BEAM ...Jul 23, 2001 · I was doing a deflection check on a 12 metre reinforced concrete simply supported beam.In the code it says compliance with the span/ effective depth ratio (20 for simply supported) will generally limit total deflections to span/250.If you have complied with depth/span ratio you do not need to check deflection, unless you have other requirements. I had the same results before....1Deflection check of a 12m beam is not very simple. You cannot rely only on span-depth ratio. I would suggest to consider post-tensioning.
