Mitch, I found the article very insightful, but I wonder if we're asking too much of a public numb to visible damage in a field where the difference between critical issues and cosmetic damage is not obvious. I love explaining lateral-torsional buckling because it's so intuitive once you can picture ...

Hello Shreyans, Can you clarify what you are asking? I'm not seeing a question in your post. ------------------------------ Christian Parker P.E., M.ASCE Structural Project Engineer Chicago IL ------------------------------

I had just entered practice when this thought first occurred to me, and I remember being alarmed and getting very curious. I eventually concluded that this is not cause for concern. If we assume no correlation between wind and seismic (more on that later), the probability of a 700-year design wind ...

I think in the instance of ballasted solar arrays, using D+0.6W vs. 0.6D+0.6W makes a significant difference, since the design output is the required amount of dead load rather than member strength. You'll specify 40% less ballast if you design for 0.6D+0.6W. I certainly see your point on geotech. ...

Intriguing update to this discussion: I stumbled upon a recent controversy over ballasted solar panel uplift design that has resulted in SEAOC issuing a formal statement to clarify proper design practices. The magazine article elaborating on SEAOC's statement reads, in part: "The 0.6 factor applied ...
