Performance-based seismic design (PBSD) of woodframe structures is currently in its early research stages with only several preliminary proposals in existence. This paper presents the design method, testing approach, and results of the first woodframe structure ever designed based solely on US FEMA 356 inter-story drift guidelines. Initially, a variation of the incremental dynamic analysis [1] method, termed incremental mass analysis (IMA), is used to design the woodframe structure. The seismic mass was selected based on the combination of seismic hazard and performance level based on the results of the IMA. One key feature of this study was that non-structural finishes are taken into design consideration to enable investigation of FEMA 356 pre-standard expected performance levels over the range of these variables. The comparison between FEMA 356 expected and experimentally observed for both structural and non-structural performance will also be presented.
