OpenSRA: Software and Publications Now Available

April 27, 2023

PEER is pleased to announce the publication of software and reports from the major research initiative, “Performance-Based Earthquake Engineering Assessment Tool for Natural Gas Storage and Pipeline Systems,” referred to as the “OpenSRA Project.” This was a multi-year, multi-disciplinary project funded by the California Energy Commission (CEC) to develop open-source seismic risk assessment tools for natural gas infrastructure. When OpenSRA is applied appropriately for mitigation purposes, OpenSRA enables utility decision-makers to effectively allocate resources to transmission systems, which supports system reliability and safety.

The project PI, Jonathan Bray, notes that “the project team’s collaborative experimental testing and computational research efforts were incorporated into OpenSRA software, and they advance the state of knowledge of gas transmission systems. Feedback and comments from the project Technical Advisory Committee also helped focus the development of OpenSRA.”

Details of the project description, publications and products, research tasks, user workshop, and related news about presentations by project team members can be found on the project website at

An overview of the project is documented in a CEC report “Performance-Based Earthquake Engineering Assessment Tool for Natural Gas Storage and Pipeline Systems, Final Project Report", written by Micaela Largent, Jennie Watson-Lamprey, Jonathan Bray, and Norman Abrahamson. Detailed technical reports will be published as PEER Research Reports in the next few months.

The OpenSRA team will continue to engage the stakeholder, practitioner, and research community with this important initiative. Please contact Dr. Jennie Watson-Lamprey ( with inquiries or expressions of interest.
