Reliability-based Capacity Rating of Wood Shear Walls under Seismic Loading
Keywords:
Wood shearwall, capacity rating, Action Reduction FactorAbstract
The purpose of this study was generate the reliability-based seismic capacity rating of wood shear walls. The rating is based on the seismic design provision of the 1994 Uniform Building Code. The shear wall resistance was established based on the provision of Eurocode 5, (2004). Uncertainties in the design variables were fully accommodated. It was established that, variability in the ground motion has very serious effect on the safety of wood frame structures under seismic loading. A review of seismic design code to fully accommodate uncertainties through probabilistic design is advocated in this study. Hence, the use of the developed design chart will ensure uniform reliability in seismic capacity rating of wood shear wall.
