Follow-up ===> Technical paper on Morandi Bridge, Genoa, Italy
(OP)
This thread is closed thread815-443075: Bridge Collapse in Genoa, Italy so by way of follow-up I thought I would post the following link from Structural Engineering International with a paper entitled:

There is a lot in information in the paper on the original design and details, and also assessment and modelling of some possible collapse mechanisms.
Note the long't reinforcement ratios of 0.3% in the piers, and only 4 each Ø24 mm (2 each T & B) and 10 each Ø8 mm (5 each face) rebars in 4,500 mm deep x 180 mm thick multi-cell deck webs.

1- It made no load carrying contribution to the structure (Other than perhaps some relevant damping effect).
2- It added to the load demand of the stay cables
3- It provided a mechanism for corrosive elements to accumulate around the stay cables
4- It obscured the stay cables from any kind of visual inspection
5- It made for a handsome bridge
Could not the concrete have simply been removed when questions arose about the condition of the cables within?
