Abstract

The Severn Bridge crossing that was opened in 1966 was the first major suspension bridge to use a system of inclined hangers instead of the conventional vertical hangers. Two further large span bridges, the first Bosporus and the Humber have similar inclined hanger systems.

Investigations undertaken at UMIST have produced computer models of the Severn and Humber bridges which indicate that under certain live load traffic conditions large numbers of inclined hangers become slack during the traversing of long trains of traffic comprising a large percentage of heavy goods vehicles.

The Severn Bridge model has been modified to evaluate an alternative inclined hanger system that uses the existing cable band and deck hanger points in their original locations but produces more favourable stress ranges and eliminates the slack hanger problem. Comparisons are made with the original inclined hanger design and with an alternative vertical hanger system.
