Abstract

Metal plate connectors enhance the load transfer
by increasing the bearing area between wood member and the fastener. Because of
having many advantages, metal plate connected (MPC) wood trusses have been
widely used for over 50 years in many building applications especially in
prefabricated homes. In this study, the possibility of using Timberstrand®
laminated strand lumber (LSL) as a raw material was investigated. The behavior
and the performance of metal plate connected Timberstrand connections loaded perpendicular
to the grain in tension and shear at 0o, 45o and 90o orientations has been
examined in accordance with ANSI TPI 1995 standards. According to the test
results, Timberstrand joints performed better than solid southern pine joints
in both tension (51%) and shear (10%) loading. This means that Timberstrand LSL
has a very good potential for use in the truss fabrication industry.
