In reply to the discussion: Please stop about the pedestrian bridge collapse [View all]genxlib
(5,785 posts)10. I am not familiar with the specifics of the design
But rest assured there was reinforcement in the concrete. Concrete simply isn't suitable for spanning members without it. It seems like it was post-tensioned steel but it was definitely there. Recent reports I have seen this morning say they were adjusting the post-tensioning cables when it failed.
Early on, someone familiar with the job told me the cables and tower were only decorative and not structural. I do not know if that is true or not. I would have assumed they were structural but I am sure we will find out shortly.

The pictures that I saw looked like the large concrete piece had re-bar support.

Speculation? The bridge collapsed. Either there was bad engineering or bad materials or both.

In hindsight the Space Shuttle *WAS* stupid... it was hype and politics turned literally deadly.

That's not very accurate. The speculation is both benign and inconsequential.
