| Abstract |
This study proposes a steel?timber hybrid Glued-in Rod (GIR) beam?column connection suitable for moment-resisting frames, and investigates
its structural behavior through finite element analysis to establish an appropriate design approach. An FEA model was developed based on
previous GIR connection tests, and its validity was confirmed by comparing the initial stiffness, peak strength, and failure modes with
experimental results. The validated model was then used to construct the proposed connection, followed by parametric analysis considering
Steel section dimensions, the use of reduced beam sections, and the number of embedded reinforcing bars. The analysis revealed that the
proposed connection exhibited semi-rigid behavior in terms of initial stiffness. In addition, the connection maintained more than 80% of its
peak strength at a rotation of 0.04 rad. The parametric results further indicated that when the plastic moment of the steel beam (Mpb) is
smaller than the moment at the plastic hinge location corresponding to the peak GIR resistance (Mh,gir), yielding occurs in the steel beam
prior to rod pull-out, thereby preventing brittle failure. This study provides fundamental insight into the behavior of hybrid GIR connections
and establishes a basis for developing an appropriate design concept for such systems. |
