Abstract: The purposes of this
research are to know the influence of woods specific gravity and nail diameter
to reference design value in double shear timber connections with steel side
plates nail on four species of Indonesian commercial wood according to various
approximation analysis. Analysis is done to four values and it is compared with
other research that has been done. This research result from testing which have
done by Ziannita (2009) referred as approach of A; result of research of Sadiyo
and Sriyanto (2009) and Mansur (2009) referred as approach of B; values
referring at literature referred as approach of C and compressive-joint total
load divided by nail amount and factor of safety referred as approach of D
(Sadiyo and Sriyanto, 2009 and Mansur, 2009). Joint done by using four species
of Indonesian commercial wood which is meranti merah (Shorea leprosula), mabang
(Shorea pachyphylla), kempas (Koompassia malaccensis) and bangkirai (Shorea
laevifolia). Nails that applied in this research are nail with diameter of 4.1
mm length of 10 cm, nail with diameter of 5.2 mm length of 12.5 cm and nail
with diameter of 5.5 mm length of 15 cm. The calculation of this research is
done according to National Design Specification for Wood Construction-2005.
Analysis results indicate that wood specific gravity influence the strength of
connection, excelsior wood specific gravity will produce high strength of
connection also. This can be influenced by mechanical properties from wood such
as maximum crushing strength. Bangkirai have higher specific gravity than three
others wood but result approach of D shows that the connections assess
reference design value which is lower compared with two other woods (kempas and
mabang wood). Then, the bigger on nail diameter brings bigger strength of
connection also, but this thing depends on the conditions from nail and quality
of nail materials.
Key words: compression
loading, double shear connections, nail, reference design value, steel side
plates
