SPR-4943: An Experimental Study into the Fatigue Strength and Ductility of Builtup Steel Members with Holes made using Plasma Cutting Methods

SPR‐4841 served as a preliminary phase to this proposal, in which a literature review was conducted to evaluate current standards and existing research around the use of PACH in fatigue. The results of SPR-4841 revealed that the state of the practice for PACH is promising and suggest that plasma arc cutting could be proven acceptable as a hole making technique. In order to conclusively determine if such is the case, further experimental studies are recommended. This study proposes to fulfil the gaps in the literature related to such experimental test data. The project deliverables will be a final project report and if the technologies are found to produce holes that meet current behavior requirements, then move the research into practice through incorporation into INDOT and AASHTO Specifications.
