Serviceability check in a concrete corbel

[Edu09]

Hi Chaps,

I've designed a corbel supporting a pcc beam using the strut and tie method to calculate the reinforcement requirements.

Any thoughts on checking service conditions in RC corbels- for cracking at the face of the tension tie based on the area of concrete?

I'm not sure this is necessary but just wanting to get some thoughts and maybe get some other insights that anyone wants to offer!

Reduce the loads to SLS, then check steel stresses to your national code.

For example, the AUS code essentially has deemed-to-comply steel stresses, under which, the concrete shouldn't have greater than 0.3mm cracks.

Thanks Trenno, that's what I thought in fact and the requirements the same.

What I wonder if there's anything else I'm not considering, I could be flogging a dead horse here...

Thanks
