Error message in Required reinforcement design

Anonymous — Thu, 07 Apr 2016 15:32:50 GMT

Hello,

I am modelling an RC flat slab and looking at the long term deflections using the "required reinforcement" calculation box within the RC Design tab. I have manually created an SLS combination, which i choose to be analysed in the "SLS Limits" Option. When i run the calculation, an error message that says "required types are not ascribed to SLS combinations. calculations may be incorrect." appears. (see screenshot attached).

Why is this happening? And will it affect the deflections?

Thanks in advance,

Corey

In your case all SLS combinations will be assumed as QPR for calculations of cracked slab deflection.

HI Artur,

The SLS:QPR option is not available, why is this?

(See attached screenshot)

Thanks

Never mind, worked it out, combination code was set as BS not eurocode!
