Never seen before - non- orthogonal steel beam construction

Never seen before - non- orthogonal steel beam construction

(OP)
Good Day All,

I am designing a steel frame, mixed commercial/residential, multistory building.
The load bearing steel frame will have cuboctohedron joints.
The resulting interior space is a rhombic dodecahedron.

The cuboctohedron joints are joined to the beams on the triangular faces.
The 6-pointed star is to align triangular beams on the joint faces.

The 3 meter floor-to-ceiling height is demonstrated on this rhombic dodecahedron.
The edge, i.e. distance between the joint centers, is about 4.5 meters.

This is basic cell with rudimentary roof, ceiling and floor.

Here are 3 views of a multi-cell, 2 story complex.

I'm interested in:
1. a structural engineer experienced with this configuration AND/OR
2. a load analysis to arrive at a steel cost per square foot of usable space.

I hope you can show me that this has been done before.

Sincerely,

It sounds like you need to hire an engineer.
