Abstract

Performance of metal-plate-connected (MPC) wood-truss-joints constructed with Turkish calabrian pine was investigated. Total of 120 joints were constructed using 38 mm by 89 mm lumber and three different sizes of metal plate connectors. joints Ultimate strength, stiffness, and load at critical slip values were evaluated using four-way plate test method. Effect of metal plate size and test method on the ultimate strength, stiffness, and load at critical slip values was also investigated. Results indicate that method of loading and plate size significantly influence the Ultimate strength, load at critical slip and stiffness values of the joints. Among the splice joints tested, these was no significant difference between 76 x 102 and 76 x 152 mm plates in strength. AA orientation had higher strength and load at critical slip values than EA orientation, but similar stiffness properties of EA orientation. For the perpendicular joints tested; plate orientation and size did not influence stiffness. Results of this study indicate that Turkish calabrian pine lumber can be used in truss manufacturing.
