Bending and shear load test on beams taken from the C2sx span and tested on the C3sx span.

This second phase of phase 2 involves the execution of non-destructive tests and structural monitoring techniques during bending and shear load tests on twin beams taken from the C2sx span and tested on the C3sx span.

Activities

  • Transformation of the C3sx span into a laboratory for bending load tests on twin beams from the C2sx span
  • Characterization tests of the twin beams selected from the C2sx span
  • Bending load test on the twin beams selected from the C2sx span
  • Dismantling and dismantling of double beams with bending heads
  • Transformation of the C3sx span to a laboratory for shear load tests on double beams coming from the C2sx span
  • Shear load test on the twin beams selected from the C2sx span
  • Dismantling and dismounting of the double beams

Targets:

  • Experimentally test the bending and shearing capacity of a structural element in post-tensioned c.a.p.
  • Check of the accuracy of the a priori estimation of the bending and shearing load-bearing capacity of a structural element in post-tensile c.a.p. Â
  • Validation of the acoustic emission-based diagnostic methodologies through the correlation between test results and the damage state induced on the structural element
  • Validation of the Digital Image Correlation monitoring methodologies by correlating test results with those from parallel monitoring sensors (flexometers)
  • Collection of additional information for validating steel side stress release tests.
