The timber bolted connection

This paper study the safety factor of timber connection designed with PPKI SNI-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 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)
