Going Beyond Conventional 1D Site Response Analysis in RSSeismic

Join us for a comprehensive webinar session on bi-directional shaking, liquefaction modeling with phase transformation, ground settlement, advanced ground motion workflows and Python scripting.

About This Webinar

This webinar explores how the latest advancements in RSSeismic are redefining the capabilities of 1D seismic site response analysis by addressing long-standing limitations. The new release introduces a finite element–based simulation platform featuring an advanced cyclic soil model, while maintaining the efficient and intuitive workflow familiar to RSSeismic users. We will also highlight enhancements to the Ground Motion Manager, enabling a more flexible and integrated workflow for developing target-spectrum-consistent ground motion suites. In addition, the session will demonstrate how Python-based automation can streamline analyses and support scalable, high-efficiency modeling.

What You’ll Learn

• How to perform fully coupled, effective stress, finite element–based 1D site response analyses with bi-directional shaking using ground motion pairs to evaluate pore pressure generation, liquefaction with phase transformation, and seismic settlement—without relying on empirical multidirectional factors.
• How to manage ground motion pairs using the new Bi-Directional Shaking Mode, review geometric mean response spectra and Effective Amplitude Spectra, and apply both motion components simultaneously in analysis.
• How to use the enhanced Ground Motion Manager to retrieve target spectra from U.S. and European design codes, and select and scale ground motion pairs from publicly available databases to match target spectra.
• How to leverage Python scripting in RSSeismic to automate workflows, build models, and batch-process analyses and results, particularly for large-scale studies involving uncertainty.

Webinar Hosts: Dr. Youssef Hashash, University of Illinois Urbana-Champaign, Dylan Centella, Geotechnical Product Manager at Rocscience
