Lateral Load-Bearing Capacity of Nailed Joints Based on the Yield Theory: Theoretical Development

摘要

A European-based yield theory using a material science approach predicts the ultimate lateral load of mailed joints with different joint configurations. The original theory is presented here and extended to include steel-to-wood joints and joints with a layer of insulation (or gap) between joint members. Formulas provide ultimate load for wood-to-wood and steel-to-wood joints and joints with unequal wood strength. A final formula represents the relationship between the wood's embedding stress and deformation not on the traditional assumption of plasticity, but as a fourth-root curve.
