What shapes of columns/beams allowed in Eurocode 2?

[Pretty Girl7]

I noticed in clause 9.5.2(3) in BS EN 1992-1-1:2004, the polygonal shapes are allowed to design.

However, I'm wondering is it possible to design "any" polygonal shape of column or a beam. For instance, a triangular column. If it's possible, where can I find the clause that describes the triangular columns etc.

By definition , A polygon is a closed shape formed by ’n' line segments, in which every segment meets at the end point of the other, & n is a natural number ≥ 3. So , a triangle meets these conditions.

However in this case , the polygon shall be understood pentagonal, octagonal ..etc

Pls look minimum dimensions for columns ..

There's nothing to stop you designing a triangular column but you'd need to go back to first principles. It may be very difficult to get it to work with moments, but a pure compression column may work.

However I suspect it'd be far easier and more practical to design a circular column and add non-structural pointy bits to make it a triangle.
