Comparative test methods for evaluating shear strength of structural lumber

Creator:: Riyanto, Djoko S.
Abstract:: Five different test methods to determine the parallel-to-grain shear strength of Douglas-fir structural lumber were compared. Four methods assessed the shear strength of lumber sections having a full nominal two by four inch cross-section. These were: three-point bending, four-point bending, five-point bending, and torsion. The fifth method was the ASTM...

Evaluation of creep behavior of structural lumber in a natural environment

Creator:: Shen, Yuanhua
Abstract:: In order to describe long term creep behavior of structural lumber in a natural environment, a bending test with twenty Douglas-Fir beams subjected to a constant load was set up in an open shed in the Forest Research Laboratory at Oregon State University. Deflections of the beams were measured along...

Short-term duration of load and cyclic performance of metal-plate-connected truss joints

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...

Dynamic behavior of metal-plate-connected wood truss joints

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...

Behavior of metal-plate-connected wood truss joints under wind and impact loads

Creator:: Redlinger, Mark J., 1972-
Abstract:: The objective of this research is to understand the behavior of metal-plate- connected (MPC) joints by examining actual MPC truss heel and tension splice joints subjected to hurricane wind load simulations and impact loads. A hurricane wind load simulation was applied to MPC heel joints to determine if a large...

A practical method to analyze the system effects of a metal-plate-connected wood truss assembly

Creator:: Dung, Da-Ren
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...

Small-scale modeling of metal-plate-connected wood truss joints

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...

A practical approach to model the behavior of a metal-plate-connected wood truss system

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...

Analytical and experimental investigation of the behavior of metal-plate-connected wood truss joints

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...
