Active control of extremely prestressed simple supported composite bridges
More than 600,000 US bridges are considered to be in need of rehabilitation. More than 90 Billion US Dollars is the estimated amount of money required. According to the National Bridge Inventory, 18.5% of those bridges are structurally deficient. Many methods of rehabilitation have been sought out …
