Abstract
The slip capacity of HSGB joints with thickness difference between jointed plates is investigated by both FEM analysis and simplified formula derived from beam theory considering shear deformation. The accuracy of FEM analysis and proposed formula is examined by the comparison to the experimental data. Summarizing the FEM results and characteristic figures by simplified formula, following proposal is suggested for the design and fabrication of HSGB joints. The allowable thickness difference between jointed plates should be limited within 1mm for ordinary thickness splice plates. For thick splice plate beyond 16mm, the inner edge distance should be taken larger value than 40mm corresponding to splice plate thickness adding thickness difference limitation 1mm.
