Collapse of steel structure

This video shows the collapse of the steel structure, probably due to the inadequate design of the structure. This video shows two important phenomena for engineers, that structure can collapse under their own dead load if they are not properly designed as in this video the structure failed during the installation. Secondly, shows the ductility of the steel structure while collapsing and giving enough time to realize that structure is falling. There might be other possible reasons for the collapse, please comment if you can think of other causes of failure. Hopefully, no one is hurt in this video.

At least it was creaking and popping and gave them enough notice. It looks like everyone had time to get clear.

A build back better program was instituted the following day.

Pre-Engineered building erection101. Build the brace bays first with all required bracing, x-bracing, girts, & perlins. or, this happens.

Looks like torsional lateral buckling of the roof beams. Once they fail, everything else follows fit.

Its a clearcut design failure... in most turnkey projects a single agency does the design & implementation. So, in order to make their bid low they use less steel to win the bid which directly impact the structure. That is why Design & implementation always should be carried out by separate agencies.

That’s what happens when we lean on something at work lol

[pintoscribbles]

Didn’t see no x Bracing in roof or walls that’s why it fell

The building looks like it was built out of noodles.

Build a Quonset Roof & hold up the Steel beams & girders with the Roof. Quonset Huts never collapse.

So that’s what this bag of washers is for

Not enough triangles (either in the design or completed at this point in the manufacturing process).

[MissionaryForMexico]

Amateurs and no cross bracing installed during assembly!

Mam nadzieje że nikomu nic się nie stało.

[doneown]

, well, this is happening more frequently , even here in US. OSHA would be all over this, if in, say, Florida!!😢

[siriosstar]

someone became unemployed after that fiasco .
