Precast Tunnel Segment - Bending Test

Barchip reinforced precast segments of internal diameter 2.07m were tested for bending loads.

The load was applied via a hydraulic ram fitted to a steel RSJ beam across the inside face of the segment.

28 day compressive strength cube results were 63.3 MPa.

Test 1 using 7Kg/m³ fibres.

Test date 07/10/02.

  • First crack occurred at 11.5 tonnes, no increase in load could be applied.
  • The load then fell back to 9.5 tonnes and held.
  • After releasing the load the cracks closed up but could still be seen.

Test 2 using 7Kg/m³ fibres.

Test date 07/10/02.

  • First crack occurred at 11.0 tonnes, an increase of load could be applied to a maximum of 11.5 tonnes.
  • The load then fell back to 9.5 tonnes and held.
  • After releasing the load the cracks closed up but could still be seen.
