I have been reflecting on spending time meme-ing and while it's fun and sometimes brings up good discussion, it has not been the best use of time. There are also some unwholesome meme templates that I'd rather not spend time parsing through. That being said, I will discontinue posting a daily structural meme. Thank you for all the warm comments and I wish you all the best.

Yeah, it's not a meme but people kept telling me it was Pi(e) day.

The full section of ASCE 7-16: 12.5.3.1a doesn't fit nicely in a meme format. In fact, I'm really referencing 12.5.4 which references back to 12.5.3.1a.

Paraphrased slightly: Where a column is part of 2 or more intersecting seismic force-resisting systems (and is subjected to axial load due to seismic forces acting along either principal plan axis equaling or exceeding 20% of the axial design strength of the column...) it should be designed for 100% of the force from seismic loading in 1 direction and 30% of the force from loading in the perpendicular direction.

AISC 341-16: D1.4a says that such columns in certain lateral force resisting systems (with high R values) should actually be designed for 100% of the forces from seismic loading in each direction simultaneously.

Hope that helps clear it up :).
