Why square bases to Elevated? |
|

Posted by geoffc on Thu Sep 26 09:55:21 2024 I was driving under the Macdonald Ave Elevated (F line) and I see they redid the base posts for each of the support columns. Now they are cubish squares with sharp edges.My first thought was, why a flat face for a collision which seems like would do more damage to car, and to support column. So I said to mysefl, why not rotate that square 45 degress, so the sharp point is into traffic, so most hits would hit a slanted slope directing the energy away from the post. But then I said, maybe round that sharp edge so it is not a damaging item in a collision and I realized i talked myself into asking, why squares and not circular bases of concrete? So why did they make the support columns squares and not round? |
