A DISCUSSION OF EVALUATION METHODS FOR SPLITTING AND SHEAR FAILURE BY CURRENT STANDARD EQUATIONS FOR DRIFT-PINED JOINT WITH INSERTED PLATE AT THE END OF GLULAM-BEAM

Abstract

We conducted loading tests using steel plate-inserted joints with drift pins at the beam ends of glulam beams. The ultimate strength formulas for these joints are the splitting and shear resistance, but their applicability is unclear.

We observed the fracture properties during the tests and defined each fracture type’s characteristics. Material experiments were conducted for each fracture property, and the 5% lower limit was applied to the current standard equation. A positive correlation was observed between the calculated and experimental values. Additionally, using the proposed values in this study improved the accuracy of determining the fracture properties.
