EVALUATING BEARING PROPERTIES OF WOOD PEG CONNECTION USING FOUR DIFFERENT TEST METHODS
Keywords:
Bearing properties, Connection, Digital image correlation, Stress, Strain, Wood pegAbstract
The objective of this study was to evaluate appropriate test methods for the bearing properties of wood peg connection using four different test methods: ASTM D 5764 (2013), the method of Church and Tew (1997), the method of Schmidt and Daniels (1999), and the method of Schmidt and Mackay (1997). Bearing properties of wood peg connection were compared using digital image correlation. Although ASTM D 5764 (2013), the method of Church and Tew (1997), or the method of Schmidt and Daniels (1999) could not differentiate bearing properties by peg orientation, the method of Schmidt and Mackay (1997) could differentiate such properties by peg orientation. ASTM D 5764 (2013), the method of Church and Tew (1997), and the method of Schmidt and Daniels (1999) created unrealistic strain distributions which affected yield load determined from the load–displacement curve. The method of Schmidt and Mackay (1997) showed the highest strain distribution at the bearing area between the wood peg and the main member, resulting in load–displacement curve by bearing mainly. These results suggest that the method of Schmidt and Mackay (1997) could determine the bearing properties of wood peg connection.
