The project involved both the testing of typical linkage bar assemblies and a review of analysis procedures used to determine the earthquake induced forces in bridge span linkage systems.
Linkage assemblies formed from a number of different types of steel bar were tested for strength, ductility and fracture toughness. An initial test on one bar type was followed by three tests on each of 12 types and two tests on one further type.
The analysis procedures that are currently used to evaluate the earthquake induced forces in linkage assemblies that restrain bridge spans were reviewed. Recommendations are made on the procedures best suited for application in New Zealand.
