A West Virginia University engineering expert believes a design fault may be responsible for the collapse of a newly installed pedestrian bridge at Florida International University that killed several people.
Hota GangaRao compares post tension cables to a piano and says they should have been ‘fine tuned’ throughout the building process.
Cracks were seen in the bridge a few days before the failure.
The completed bridge was in place for five days before collapsing. The strength limits may have been exceeded during this short time.
He says a visceral elastic stress failure in the structure could be to blame.
“Once we understand that component, that aspect better, we can easily design it without any major safety related issues during construction,” said Hota GangaRao, Professor of Civil and Environmental Engineering.
GangaRao says the investigation is too premature to conclude the exact reasoning of why the bridge collapsed.
