Radical proposals for hotspot stress design

Drafts of the AISC guide for hotspot stress contained several radical technical proposals that could benefit from exposure and peer review before publication in the design guide. These are:
- S-N slope of -1/3.6 with no transition knee,
- notch stress size effect based on mesh density, and
- thickness-dependent strain limits for TxT meshing.
These proposals are presented here along with their supporting data.
