A lot of work on ASCE 7 updates happens behind the scenes, and progress is more iterative than linear—we often don’t see the full picture until changes are widely used, sometimes ~10 years after they’re proposed, reviewed, approved, published, and implemented. As our community wraps proposals for ASCE 7-28, ASCE 7-22 becomes enforceable. On ground motions, 7-22 brings two especially important changes from 7-16: • Multi-Period Response Spectrum (MPRS). Replaces traditional site-amplification factors (Fa, Fv) applied to a two-period spectrum. This isn’t just a new spectral shape: spectra are computed explicitly for each Vs30, with expanded site-class coverage—a fundamental shift in how site effects enter design. • NGA-East for the Central & Eastern U.S. (CEUS). CEUS source, site, and propagation characteristics differ from the West, so site-amplification trends don’t always match the “softer soil = more amplification” intuition—especially when nonlinear site effects are considered. With limited recordings, numerical simulations fill gaps—each with valid ranges and, at times, extrapolation. A small correction to the current CEUS implementation is now moving through professional-organization voting—but it’s prompting broader questions about the fundamental changes already in 7-22. For a deep dive, watch Prof. Jon Stewart (UCLA) present to the SEAOSC Seismology & Hazard Committee on the technical aspects of ASCE 7’s CEUS site amplification. One common concern is the limited CEUS data relative to the West, which can tempt us to lean on NGA-West models; however, available evidence shows CEUS behavior doesn’t follow those trends. Prof. Stewart addresses this directly in the Q&A. Join this channel to get access to perks: https://www.youtube.com/channel/UC2DmxFJif00XuMFNhSLIeSA/join

This webinar introduces DesignSafe as a unified platform for advancing natural hazards research, offering integrated tools for data management, interactive modeling, and high-performance computing. Using OpenSees as the primary case study, participants will explore how to design and scale computational workflows — from small exploratory runs to automated HPC pipelines. The session emphasizes the complete scientific workflow lifecycle, including model setup, job submission, monitoring, and results management. While focused on earthquake engineering, the strategies presented are broadly transferable to other domains such as CFD, climate modeling, and structural simulation.
