Abstract:: This study presents a practical method to model an actual Metal-Plate- Connected (MPC) roof truss assembly using a commercial program, SAP2000, to investigate its system performance. Truss assembly modeling was examined because the conventional single truss design method ignores system effects, such as variability of modulus of elasticity (MOE), interaction...

Creator:: Waltz, Miles E.
Abstract:: As part of a roof framing system, light-frame wood trusses often require lateral bracing to reduce the effective length for flexural buckling of compression web members. This observational research investigates the design requirements for discrete compression web bracing intended to provide such lateral support. Four simple brace analysis methods based...

Creator:: Freilinger, Shawn M. Wicks
Abstract:: The objective of this research was to evaluate the duration of load factor for metal-plate-connected (MPC) truss joints subjected to various cyclic loading conditions. Heel and tension-splice joints from a standard 30-foot span Fink truss constructed from nominal 2x4 Douglas-fir lumber were tested. A testing frame similar to that developed...

Creator:: Kittel, Mark
Abstract:: The objective of this research was to develop a one-third scale model of full-size (prototype) metal-plate-connected (MPC) wood truss joints using similitude theory. The prototype metal connector plates in MPC joints were modeled using thin galvanized sheet metal and short staples. Truss grade wood material was ripped to one-third scale...

Creator:: Li, Zhong
Abstract:: Metal-plate-connected (MPC) trusses have traditionally been designed based on a tributary load distribution and a simplified truss model. This design method ignores the load-sharing and composite action in MPC roof truss systems, the semi-rigidity of MPC joints, and joint eccentricity. The main objective of this study was to provide a...

Creator:: Kent, Scott M.
Abstract:: The objectives of this research were to evaluate the behavior of actual metal-plate-connected (MPC) tension-splice and heel wood truss joints under seismic loads from the Northridge earthquake (tension-splice joints only) and under loads from a large artificial earthquake (1.0 g's and 0.67 g's maximum horizontal and vertical accelerations, respectively). A...

Creator:: Vatovec, Milan
Abstract:: A commercially available, three-dimensional (3-D) finite-element (FE) analysis program was used to model metal-plate-connected (MPC) joints in wooden trusses. The model's features included consideration of material properties, teeth-to-grain-to-direction- of-force orientation, and wood-to-wood contact. Non-linear spring elements, placed on the wood surface between wood and plate, were used to represent wood-to-teeth...
