Abstract
The upgrading of suspension bridges, if required, is an extremely costly procedure. It is therefore worth some considerable effort on the part of the engineer to determine if rehabilitation is in fact really needed for the safety of the bridge or whether it is only required in order to satisfy a code.
The importance is emphasized of taking a critical look at criteria, including traffic and wind loads, aerodynamic stability and seismic response. Recent developments in wind tunnel testing are presented, with observations on long-term cable stretch, reliability of temperature measurements and the use of limit states design. Three examples are taken from suspension bridges ranging in span from under 200 m to over 800 m.
