The purpose of this task is to select and scale a set of earthquake ground motion records suitable for analytical (i.e., nonlinear response history analysis) and experimental (i.e., laboratory testing) investigations for this project. The project team will employ the PEER NGA-West2 database, which was developed for shallow crustal earthquakes in active tectonic regions, to select and scale ground motions.
- The list of all ground motions selected and scaled by WG3.1 is in Appendix A.1 (UHS suites) and Appendix A.2 (CS suites) of the WG3.1 report (see below). This appendix includes NGA-West2 Record Sequence Numbers (RSNs), which are unique record numbers, along with scale factors used for each recording. NGA-West2 records can be accessed from https://ngawest2.berkeley.edu.
- The results of probabilistic seismic hazard analysis (PSHA) as part of WG3.1 are part of the Appendix B of the WG3.1 report (see below).
- The final selected and scaled ground motions used in the structural analyses are provided in the archived data for Working Group 5.

Appendices
The purpose of this task is to determine if currently available loading protocols are appropriate for the experimental testing program, and if needed, provide an update to those loading protocols. This task is tied in with the development of the Index Buildings (Working Group 2), in which a set of representative wood-frame buildings on raised foundations in California are compiled. The loading protocols developed will be tailored for this target building set.
