That is where the major transisition was from box column to I beam construction. There was no concrete inside or over those columns. What's the possibility of HSS columns filled with concrete? I'll do some searching. I want to know when this technique was used first. Then go on from there. From studying thousands of pics from the aftermath, I have seen no sign of concrete ever being inside those columns. What did amaze me though is the clean breaks at the welded seams. Whenever anything I have welded failed, it was always adjacent to the weld and never at the weld itself.
