rc beam reinf(EC2)

[monchie]

Hello,

I'm just wondering why the reinf areas formula to EC2 in ETABS is different to IStructE manual(EC2). The former gives more reinf areas in the process(pls. see attached screenshot).

Any ideas will be greatly appreciated.

Any comments?

Generally the structural software use the same basic formulas, as given in relevant codes. However, sometimes in a different format, to suit programming of computer code. This might be such a case. You may check it by using the two formulas on some practical design example and comparing their results.

A good structural engineer is often a blessing for others.

Thanks PSEPK, but the existing formulae used by ETABS in Eurocode(RC reinf areas for beam) is quite high. I'm just wondering if any ETABS user(Eurocode) have the same experience with me.
