Crack width. AQB

Hello everyone,

I’m trying to do SLS design for crack width for a concrete beam in AQB. I’m just using example ru_snip.dat with some additions. I’ve added task for SLS design. But if I change crack width, reinforcement result is the same.

The code I’ve added (Loadcase 10 is just for test):

+PROG ASE URS:10
HEAD
LC 10
LCC 2 fact 5
END

+PROG AQB urs:9 Design SLS (Beams) HEAD SLS design beams PAGE UNII 0 NSTR S0 CRAC yes CW 0.1 crack width
BEAM TYPE BEAM
REIN LCR 2
DESI STAT serv
LC 10
END

Could you please help me to find the problem? May AQB use tables (NSTR CRACK TAB) for crack width in all cases even if I use NSTR SCRAC yes CW 0.1?

Best regards

Helen

Hello!

That’s a great example. Thanks!
But I’m from Russia. And if I change the norm with NORM ‘SP’ NDC ‘63-13330’, I’ll find strange result.
That would be great, if you helped me with this problem

Best regards
