Registration is now open for the 2025 PEER Annual Meeting which will be held March 25-26, 2025, in the Banatao Auditorium on the UC Berkeley campus. The meeting will feature PEER research in the fields of performance-based engineering and resilience, with focus on buildings and infrastructure subjected to various geohazards, tsunami and fire. In addition, sessions will be formatted for more detailed discussion and engagement to identify areas where research and development are needed.

PEER has published Report No. 2024/09: "Correlation of Ground Motion Duration with Spectral Acceleration and Implications for Expected Bridge Performance." It was authored by Maria Camila Lopez Ruiz and Tracy Becker, Department of Civil and Environmental Engineering, University of California, Berkeley; Micaela Largent and Jennie Watson-Lamprey, Slate Geotechnical Consultants, Inc.

PEER has published Report No. 2024/08: "Experimental and Numerical Investigation of Ballistic Impact Response of Polymethylmetacrylate." It was authored by Youngjoon Jeon and Khalid M. Mosalam, Department of Civil and Environmental Engineering, University of California, Berkeley.
