Safety Factor of Timber Bolted-Connection Designed with SNI-5 (2002)
Abstract: This paper study the
safety factor of timber connection designed with PKKI NI-5 (2002). Johansen
yield model is used to evaluate the nominal design value of single bolted
connection. Double-shear bolted connection, with the side members and the main
member from wood, is chosen for this study. A comparison study of safety factor
between SNI-5 (2002) and NDS for timber construction of U.S (1997) is also conducted.
Finally, the safety factor is analyzed for both directions parallel and
perpendicular to wood grain of four possible yield modes. From the study, both
SNI-5 (2002) and NDS (1997) use higher safety factor for bolted connection
sustaining load perpendicular to grain than that sustaining load parallel to
grain. Smaller safety factor is used in both codes when the plastic hinge of
bolt is created such as the yield modes IIIs and IV. However, in this case, the
safety factor of NDS is significantly much higher than that of SNI-5
(2002).
