Firstly god rest the soul who died on the top deck as it fell, and same to all the other victims.
As for the other top deck survivors, the speed that thing went, they won't have has time to sh1t themselves let alone consider the reason they were falling.
I'm also starting to think about the...
The more I think about this the more concerns I have around the length of the main deck and lack of a proper 'I' beam.
This is a 50m concrete structure supported at either end with very little useful stiffening to stop longitudinal deflection.
You have a handful of asymmetrical concrete trusses...
Does anyone else not like the V shaped profile under the deck, and the SPMT using quite narrow wedge shaped load spreaders on top the shoring?
Hope they loaded it in the right places too, that truss arrangement has some significant load complexities.
Just in case anyone is interested in a rough idea of the tension / compression loading of the trusses when:
A-In transit supported underneath in 2 places mid span
B-In Situ supported at either end of the span
These are not to scale or necessarily accurate, but give a general idea. Draw your own...
