Slab reinforcement cover

JPNR87 — Tue, 25 Feb 2020 09:20:01 GMT

Hi,

according to Eurocode nominal cover (for calculations):

In Robot is cover defined:

For example hand calculation demands nominal cover 25 mm (10mm deviation+15mm minimum cover for plate calculation).

My question is how nominal cover for plate design is calculated and inserted in Robot to have 25 mm nominal cover ?

Thanks for answers!

Hi @JPNR87

While slab reinforcement parameters definition cmin is defined on reinforcement tab

and dcdev is defined in Deviations window

Then cover taken for calculation is c=cmin+dcdev.

So to define cnom 25 mm you should define c=15 mm then dcdev=10 mm

Hi!

opening this threat once more with additional question.

In case of two-way working slabs how does Robot consider lever arm for none-main rebar. For example if I have slab with Cnom= 25 mm with 10 mm rebars does Robot consider automatically c2=25+10+10/2.

Thanks for answers!
