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...

Many nondestructive techniques for structural health
A computer program called SAPWOOD which possesses the
capability of performing linear or nonlinear, static or
dynamic response including seismic excitation for wood-framed
buildings with semirigid connection systems is
presented in this study. Program SAPWOOD is a modification
of the program NONSAP by adding new elements such as a
linkage...
Since 2004 there have been multiple devastating tsunamis around the globe triggered by large magnitude earthquakes; with the most recent being the Tohoku, Japan tsunami in March 2011. These tsunamis have caused significant loss of life and damage to the coastal communities impacted by these powerful waves. The resulting devastation...
Key parts of the lateral force resisting system in wood-frame buildings
are the shearwafls and the connections. The connections in wooden buildings
are the primary source of ductility and energy dissipation; these are essential
properties when buildings are exposed to lateral forces, such as wind and
earthquakes. Shearwall design is...
Nailed connections have nonlinear load-displacement
relations. Modeling these connections in an assembled
structure would require a great amount of computational time
because of the large number of degrees of freedom.
Replacing these connections with energetically-equivalent
nonlinear springs reduces the number of degrees of freedom,
and leads to computational efficiency in...
The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...
