Project Abstract
The 1st-year scope consisted of one 2-hour meeting (3 – 5 p.m.) at SCEC on April 3, 2013; the meeting was held in conjunction with the GMSV-TAG committee meeting earlier in the day. The 1st meeting covered the following agenda items: (1) finalize committee membership, (2) establish technical tasks and the resources to accomplish these tasks, (3) create organization chart and identify the committee members to lead and participate in each task, and (4) establish a schedule for the project.
Intellectual Merit Crouse presented a preliminary 6-yr schedule to complete the pilot project of producing long period response spectral acceleration maps of the Los Angeles Metropolitan region. An additional 2 yrs was estimated to pass through the NEHRP Provisions Update Committee next code cycle.
Broader Impacts The SCEC UGMS Committee is tasked to develop long-period response spectral acceleration maps for Los Angeles region for inclusion in NEHRP and ASCE 7 Seismic Provisions and in Los Angeles City Building Code. The maps would be based on 3-D numerical ground-motion simulations, and ground motions computed using latest empirical ground-motion prediction equations from the PEER NGA project. This project is coordinated with (1) the SCEC Ground Motion Simulation Validation Technical Activity Group (GMSV-TAG), (2) other SCEC projects, such as CyberShake and UCERF, and (3) the USGS national seismic hazard mapping project.
