Industrial History: Steel is stronger in tension than compression

I've talked before about members in a truss bridge that are in tension are cheaper to build than members that are in compression. When I saw this photo I was reminded that steel is weaker in compression.

And when I saw this photo a week later, I decided that was close enough for my "2 in 2" rule to write about steel in compression.

Covered Hopper MOCX 426425 appears to be the victim of a very hard shove or a collision. Andy Cassidy took this shot in the CP yard in Coquitlam BC in June 2020. www.canadianrailwayobservations.com
Cameron Blanchard Looks like hump damage.
Tom Srb Looks like a Trinity Industry built car, they never did hold up even in normal usage situations.
Dave Drake Took more than a hard shove . Iol
John White Hit pretty hard to bend the sills like that.
Jerry Maddax I’m thinkin,a smidge over 4 mph

And the demonstrations just kept on coming.

Walter A. Keil A fully loaded reefer like I assume that one is need to spread a bar across the top so it picks up straight up not towards the center.
Jim Snowy With the slings angled like that, there is compressive force created in the container. Normally they are lifted with a spreader so the force is purely lifting.

David Carnes commented on the above video
Containers are designed to be lifted from bottom 4 corners when loaded. Top will overstress and buckle them.

Brett Patrick David Carnes They're always top lifted at container terminals, but the jigs they lift with eliminate the included angle component which caused this failure.
Paul Marcati Directions on the side lol
Never pick loaded container from top pick points
Always use lower pick points

Any old truss bridge shows that members in tension are much cheaper (less metal and less fabrication) than members in compression. This is an example of v-lacing compression members.

Old Renwick Road

HAER explains that the truss members were fabricated in their shop and then shipped to the site and assembled using a local work crew under the supervision of a field agent who worked for the bridge company.

Morris Terminal RR Bridge over I&M Canal

This Big Four Bridge over the Ohio River is so big that even the "simple" members are rather substantial.

Another bridge that has been converted to pedestrian use and allowed me to get up close and personal with the truss members was the 135th Street Bridge in Romeoville, IL.

This bridge is basically a Warren Truss. They evidently don't have pure tension members. But the vertical members are thinner than the diagonal members.
