Engineering Development • Stage 1

– Truss composite bridges bridge– Post-cure bolt joint for 80°C design temperature

• Stage 2– Grout filled composite truss bridge for long span– Ambient cure bolt joint for 80°C design temperature

• Design criteria (AS2156, AS5100, AS1170)- Dead Load : 0.3 KPa- Live Load : 5.0 KPa (Pedestrian)- Vehicle load : 4 ton (Emergency vehicle at low speed)- Deflection Limit: L/250- Design temperature : up to 80 °C

Stage 1 • Structural specification

Span: 12 - 14 meters / Height : 2.0 meterTop-chord - 2 x 125SHS / Bottom-chord - 2 x 125 SHS / Webs - 1 x 250BRB

• Bolted jointDevelop post-cure glue system for 80°C design temperature Evaluate design strength for both ambient and 80°C design temperature

• Truss systemPerformance under static design load (Proof loading: AS/NZ 1170.0)Prove fatigue performance with 1,000,000 cycles of loading

Stage 2 • Structural specification

Span: 23 meters / Height : 2.2 metersTop-chord - 2 x Grout-filled 250 BRB / Bottom-chord - 2 x 250 BRB / Webs - 1 x 250 BRB

• Bolted jointFurther development, ambient cure glue system for eliminating post-cure procedure Evaluate design strength for the range of design temperature between ambient and 80°C

• Grout filled truss systemPerformance under static design load (Proof loading: AS/NZW 1170.0)Comparative study with and without grout-filling method
