CFVR1243 - Shear checking according to Eurocode 2 (2008)
Check a reinforced concrete beam subjected to shear force according to Eurocode 2 (2008)
A 5m length beam which is simply supported, has a T concrete reinforced section and is subjected to a uniform distributed load of 84 kN/m.
The aim of the example is to obtain the check criterion according to Eurocode 2 (2008).
