Abstract
This study examines the seismic force modification factors related to overstrength and ductility of wood light-frame shearwalls. Several archetypes were developed to meet different design criteria. Nonlinear static procedure, nonlinear time-history analysis, and nonlinear incremental dynamic analysis were performed. The numerical analyses were based on 2D representations of the designed archetypes. The nonlinear static analysis results revealed an overstrength factor of 2.2, which is greater than the current value of 1.7 for wood light-frame shearwalls. The findings also indicated that existing design requirements for hold-downs and the overcapacity requirement for the first and second stories may not always ensure satisfactory performance. The archetype detailed screening step proved valuable as a preliminary assessment prior to the incremental dynamic analysis in identifying critical archetypes. The results of the performance margin ratios indicated that the archetypes marginally met the life safety performance level. Overall, this study suggests a need for potential adjustments in design standards and considerations for a more comprehensive evaluation of the seismic performance of wood light-frame shearwalls. This study also found that adhering to design requirements related to certain irregularities decreased the probability of collapse in those archetypes.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
