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...

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...

Location of the neutral axis in wood beams

Creator:: Holm, Sarah C.
Abstract:: It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...

Comparison of screening, evaluation, rehabilitation and design provisions for wood-framed structures

Creator:: Baxter, Preston
Abstract:: Many publications, documents, codes and guidelines exist related to the seismic evaluation and rehabilitation design of existing buildings. This report discusses the assumptions and methods employed for investigation of two wood structures using four references: FEMA 154, FEMA 356, ASCEI per SEI 31, and 1997 UBC. The screening performed using...

Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

Creator:: Kirkham, William J.
Abstract:: There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...

Development of rapid visual screening tool for seismic evaluation of wood-frame dwellings

Creator:: Lucksiri, Kraisorn
Abstract:: During the past several decades, earthquakes have caused extensive damage to buildings, including wood-frame, single-family dwellings, in the United States. In order to mitigate future losses, existing buildings in earthquake prone areas should be evaluated for their seismic safety. This is also an important issue for buildings in Oregon due...

Practical modeling for load paths in a realistic, light-frame wood house

Creator:: Pfretzschner, Kathryn S.
Abstract:: The objective of this study was to develop and validate practical modeling methods for investigating load paths and system behavior in a realistic, light-frame wood structure. The modeling methods were validated against full-scale tests on subassemblies and an L-shaped house. The model of the L-shaped house was then modified and...

Use of Virtual Visual Sensors in the Determination of Natural Frequencies of Timber Structures for Structural Health Monitoring

Creator:: Walker, Kristopher
Abstract:: Many nondestructive techniques for structural health monitoring are subjective and based on visual observations of degradation. In addition, dynamic properties of structures are already used to obtain quantitative structural health data. However, most current data collection is limited to localized damage on the structure, rather than global response. Recent research...

The performance of wood frame shear walls under earthquake loads

Creator:: White, Kevin Bradish DelGrande
Abstract:: The overall goal of this study is to evaluate the earthquake performance of wood frame shear walls, and more specifically: (1) to compare the performance differences of fully and partially anchored walls under monotonic, cyclic, and earthquake loads, (2) to compare wall performance under earthquake loads with that of standardized...

Effects of reference displacement and damage accumulation in wood shear walls subjected to the CUREE protocol

Creator:: Langlois, Jeffrey D.
Abstract:: The objectives of this study are: (1) to evaluate the effect of reference displacement on wall behavior under fully reversed cyclic loading using the CUREE test protocol and (2) to assess damage accumulation (visible fastener damage and stiffness degradation) for the imposed drift levels. All tests were conducted on identical...
