Hydro Transmission Tower Ice Risk Reduction Program
Many power companies have their towers evaluated frequently because the accumulation of ice that can comprise any transmission tower.  We were retained to analyze BC Hydro's
H-frame type transmission tower.  A total of 156 towers were inspected, and six were variations of the H-frame designs that needed to be modeled and evaluated.

Morrison Hershfield analyzed the six towers for increased ice loads and identified overstressed members and methods to reinforce the towers.  Drawing upon years of tower inspection experience, solutions were found that were quickly adapted to the variations of the towers.  This, in turn, allowed Morrison Hershfield to provide the client with the best solutions to the stress loads that were added to the transmission towers during icing.
