Base plate thickness equivalent
Base plate thickness equivalent
(OP)
I'm designing a steel post and as the result of the calculation the required thickness of the base plate is 20mm. And the architect ask me if we can use 2- 10mm thick in order to obtain the 20mm thick(no other connection between the 2- 10mm plates except for the anchorage). Considering its a moment resisting support. Is this possible? or is there any loss in strength considering the baseplate is not monolithic. Any input will be much appreciated. thanks in advance.

For what it's worth, a single plate 20 mm thick has a section modulus (bt^/4) of two times the value of two individual 10 mm plates (not welded together).

If the plates are not welded, then simply add up the inertias of 10 mm plates, which will be less than the inertia of one 20 mm thick plate.
If the plates are welded on the edges it will depend on the dimensions and demands but a safe estimate is still adding up the inertias.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
