The 9th Spring School 2025 was hosted at the prestigious EPFL in Lausanne and represented a key event for the structural engineering and earthquake simulation community, with a strong focus on the Open System for Earthquake Engineering Simulations (OpenSees). The spring school was designed for both experienced OpenSees users and newcomers, providing an opportunity to strengthen technical skills and deepen the understanding of the software.
