Passing loads from steel columns to foundation r.c. design

[Anonymous]

Hello all,

I am having difficulty with the workflow for passing loads from a steel frame design of a portal frame to the R.C. module for design of the foundations.

I have selected the supports and then using the "Provided Reinforcement of RC Elements" to push them through to the R.C Design module. I am then selecting the manual load combinations and the correct number of the foundations appears to be generated. The loading information from the steel frame (the reaction forces at the supports) doesn't seem to translate through though which is essential to the design. What am I missing?

Ultimately I want to generate simple square foundations without any piers and simple fabric reinforcement.

Thanks.

Hi @Anonymous

Could you attach your model?

Hi Artur,

Thanks for the prompt reply. Model attached.

Try RC Elements > Load Table commands:

Hi Artur,

Thanks for this, I see the loading for all of the individual load cases. Is there a way to automatically select the most onerous load case and design the foundation to suit? Or do I have to manually go through them all and then manually input them into this dialogue?

Also, the foundation type by default has a pier, what's the best way to avoid this? I simply want a square/rectangular foundation with a bolted connection from the steel column. At this stage the baseplate size to the column is unknown with the design responsibility falling to third party.

Thanks

For the group of foundations the design is done for the loads from all combinations from each of the node which belong to this group one by one. The final foundation size is such that it is OK for all of them. If you know which one is the worst just import only this one from a model.

You need to set it each time as there is no option to save the default foundation geometry.
