Extreme torsional plan building information

Hello Everyone

I'm trying to find a plan configuration of real structures with extreme torsional irregularity Type 1a or 1b. Has any of you dealt with this problem, that could provide some information?

I'm starting to believe that is difficult to find structures with Type 1b in real world

Thank you!


RE: Extreme torsional plan building information

I'm working on two projects right now with extreme torsional irregularities (though I suspect I'll be able to get one of them down to a non-extreme irregularity).

One is a concrete building with a single core wall in the center of the building. The core is slightly offset from the exact center so coupled with accidental eccentricity it becomes an extreme torsional irregularity.

The other is an L-shaped concrete building (in plan). Extreme torsional irregularity is easy to come by with L-shaped buildings since you can get a lot of stiffness on one side depending on the core configuration.
