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...

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...

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...

System behavior of three-dimensional wood truss assemblies

Creator:: Limkatanyoo, Pranueng
Abstract:: The objective of this research is to use a three-dimensional (3D) analysis method to include 'system effects' directly in the design of light-frame roof truss assemblies. The goal of this study is to develop an improved and practical method to determine the structural performance of 3D roof truss assemblies used...

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...

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...

The effect of hold-down misplacement on the strength and stiffness of wood shear walls

Creator:: Lebeda, Dana J.
Abstract:: The objective of this study was to determine the effect of misplaced hold-downs on the static and cyclic behavior of wood shear walls. Three shear wall configurations were considered in this study. The first configuration (control) had hold-downs at the ends of the wall (wall type 1), the second configuration...

Evaluation of the torsion test as a method to determine the shear strength of structural composite lumber

Creator:: Siller, Tobias Stefan
Abstract:: Torsion test was evaluated as a method to determine the shear strength parallel to grain of full-size structural composite lumber (SCL). Experimental results of eighty-five rectangular (44 x 140 mm²) specimens were verified by finite element analysis. Laminated strand lumber (LSL), laminated veneer lumber (LVL) and parallel strand lumber (PSL)...

Full Text:: ), laminated veneer lumber (LVL) and parallel strand lumber (PSL) were tested using torsion. For comparison

Performance of partially and fully anchored wood frame shear walls under monotonic, cyclic and earthquake loads

Creator:: Seaders, Peter
Abstract:: The objectives of this study were to evaluate the performance of wood frame shear walls under monotonic, cyclic and earthquake loads by: (1) estimating the variability of shear wall performance, (2) comparing the performance of walls under each loading protocol, (3) evaluating the effects of anchorage on wall performance, and...

Slotted-bolted friction damper as a seismic energy dissipator in a braced timber frame

Creator:: Tjahyadi, Alfred
Abstract:: Friction dampers have been used successfully to dissipate seismic energy in steel and concrete structures. The application is new to timber structures. The objectives of this research were to design a slotted bolted connection (SBC) and evaluate its potential as a passive energy damper in timber brace. The research was...
