Evaluate Bearing Stress Of Glulam Using Digital Image Correlation

The goal of this study is to evaluate the effect of different sizes of drift pins (12mm, 16mm, 20mm, 30mm) and six orientations of glulam associated with pin positions (RL, TL, LR, TR, LT, RT) on bearing stress and strain distributions of glulam using digital image correlation (DIC). Different bearing stresses, strain distributions, and fracture behaviours associated with the orientation of the glulam and pin sizes were observed. As the diameter of drift pins increased, the bearing strength increased regardless of the orientation. However, the trends of failure behaviours did not change by the pin size.…
