Design of base plate of steel column

[tekno.structures]

When designing a steel connection for the base plate of a steel column using the steel connections module in RSA and specifically for the concrete cone pull-out checking, are the reinforcement bars of the concrete footing/ground beam/column pier taken into consideration?

What I mean is that, the anchors inside a foundation are almost always surrounded by steel reinforcement therefore where the cone pull-out failure plane is formed a steel bar may be passing through it which gives more resistance against cone pull-out (tension) or breaking of concrete edge (shear).

ACI 318-11 refers to this in the below pages

hi @tekno.structures 

Note that Eurocode is available

https://www.boutique.afnor.org/en-gb/standard/nf-en-19924/eurocode-2-design-of-concrete-structures-p...

The eurocode could advantageously replace the current CEB checks carried out using the steel connection module.

We can only hope that EN 1992-4:2018 is part of the next development.

Note that the draft standard prEN 1992-4:2013 (Eurocode 2: Design of concrete structures - Part 4: Design of
fastenings for use in concrete) is notified with CEB_96 by CNC2M in th following document :
