Abstract
A method of modifying the vertical profile of a cable supported bridge. The method consists of sequentially adjusting a lower end of a series of supporting cables downward relative to the bridge superstructure and sequentially adjusting an attachment structure associated with the lower end of each cable to maintain the distance each cable has been adjusted. The adjustments preferably proceeds according to a pre-specified plan known as an adjustment sequence. The preparation of an adjustment sequence according to the methods disclosed allows the modification of the vertical profile of the bridge superstructure to be completed without overstressing any bridge members, and with predictable results.
