| Summary: | This research was to investigate the properties of nail withdrawal holdings on
Kelampayan timber and were tested based on standard ASTM 01761-12 to
determine the withdrawal strength of the nails. This research only have one
parameter which is three types of nails (smooth shank nail, ring shank nail,
screw shank nail). The testing were conducted in a room with temperature of
20°C and 65% of humidity of surroundings. There were about 6 nails for
every type of nails were tested during the research conducted. The results
show that the mean of maximum load for smooth shank nail is 1473.41N with
standard deviation of 119.44N. For the ring shank nail and screw shank nail,
it shows that the mean of maximum load are 1539.08N and 2570.03 with
standard deviation 317.98N and 465.02N respectively. The withdrawal
strength of the nails were recorded as 0.13MPa for the smooth shank nails,
0.14MPa for the ring shank nails, and 0.22MPa for the screw shank nails.
This research conclude that screw shank nail had the highest withdrawal
strength compared to the smooth shank nail and ring shank nail on the
Kelampayan timber. |
