abstract = "The research presented herein describes the findings and conclusions thus far in an experimental and analytical study of the behavior of woodframe shear walls sheathed with OSB combined with drywall and/or stucco subjected to cyclic loading. Eight, 8 ft square shear wall specimens were constructed and tested using the CUREE-Caltech pseudo-static loading protocol. A total of four different configurations were investigated to quantify the performance characteristics of conventional woodframe shear walls sheathed with OSB finished with either drywall and/or stucco. Currently, ASCE 41 provisions suggest no increase in capacity, nor difference in acceptance criteria for plywood sheathed walls clad with non-structural finishes (drywall and/or stucco) citing that stucco/drywall are brittle and fail at low levels of seismicity. However, data collected from research conducted as part of an ongoing study show that there are large differences in the backbone curves. Furthermore, using the Type 1 curve (as put forth by FEMA 356/ASCE 41) for establishing the acceptance criteria of ductile subassemblies may not be a good match for the recorded data from wood sheathed walls (both with/without cladding of drywall/stucco). Lastly, when a Type 1 component behavior is fit to test data consistent with the ASCE 41 Alternative Modeling Parameters and Acceptance Criterion, the suggested Life Safety and Collapse Prevention acceptance criteria vary greatly for each of the four configurations tested.",
