| Abstract: |
The Clarence River Rail Bridge is a 478 m long steel truss girder bridge located 40 Km north of Kaikoura. The cast iron fixed and guided pinned bearings of the bridge suffered significant damage during the November 2016 Kaikoura Earthquake, likely caused by vertical seismic accelerations in excess of 1g. Replacement of the damaged cast iron guided pinned bearings involved the design of new bespoke pinned steel bearings with modern stainless steel and approved sliding material (ASM) surfaces newly introduced to AS5100.4:2017. The use of modern bearing materials and established detailing principles have led to rehabilitating an earthquake damaged 80-year-old bridge with design and construction of the earthquake repairs completed in less than 12 months. |
