Shear-out at High Tension Connections: "Chunk-out Re-examined
- A new design check, initially termed “chunk-out,” appeared in the truss design process with the adoption of TPI 1-2002.
- The appropriate technical term for chunk-out is actually “shear-out.”
- Understanding shear-out requires defining the stress distribution around the plate and comparing the magnitude of stresses to the wood shear strength under the plate.
- Future finite element stress analysis and testing has been planned in order to define the nominal stresses associated with the shear-out condition.
