Abstract
  • 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 based on new materials and a monotonic testing method, which departs from the actual situation because buildings age and are subjected to cyclic loads during wind and earthquake events. After the property losses experienced in the Loma Prieta and Northridge earthquakes, the engineering community realized there was a need to further investigate wooden shearwall performance especially with respect to condition and cyclic loading. Individual sheathing-framing connections can be designed with respect to capacity and yield mode by using the yield mode equations. However, the relationship between individual connection characteristics and the performance of a shearwall remains unclear. The objective of this study was to investigate the relationship between individual connections and shearwall performance where nail bending-yield stress (fyb) and biological deterioration of the wood were sources of variation in physical and simulation experiments.
