| Abstract |
This study proposes a classification system of the timber beam-to-column joint using various steel connectors in terms of stength and stiffness.
The classification system is developed through the relationship between the moment acting on the beam and the joint, as well as their
corresponding deflection behaviors which follow the method described at AISC provision in order to introduce semi-rigid concept in design
process. In terms of stiffness the classification criterion for partially constrained connections was derived as EI/2L, and for fully constrained
connections classification criterion was derived as 10EI/L. Considering the material properties of woods, the strength classification criterion for
semi-rigid connections was determined as 20% of the yield moment of beams, and the criterion for rigid connections was defined as equal to
or greater than the yield moment of beams. Based on the experimental results of the connection specimen adopting typical timber glued-in-rod
detail, typical timber glued-in-rod detail can be classified into partially constrrained and semi-rigid in terms of stiffness and strength,
respectively. It indicates that moment transferring mechanism at the joint should be considered in structural design process. |
