Open Source Software: MASTODON: Pioneering Multi-Hazard Analysis for Critical Infrastructure In an era where the resilience of critical infrastructure against natural disasters is paramount, MASTODON stands out as a beacon of innovation. This cutting-edge software tool offers a comprehensive solution for modeling stochastic nonlinear soil-structure interactions (NLSSI), bringing a new level of sophistication to dynamic probabilistic risk assessments. The increasing frequency and intensity of natural disasters, coupled with the critical need to safeguard infrastructure, necessitated the development of a robust modeling tool. MASTODON was conceived to meet this challenge, offering detailed simulations of how structures like nuclear facilities, dams, and bridges respond to external hazards, including seismic events. MASTODON, built upon the powerful MOOSE framework, excels in the numerical modeling of seismic soil-structure interaction. It uniquely combines structural dynamics, time integration, dynamic porous media flow, nonlinear hysteretic soil constitutive models, and geometric nonlinearities (such as gapping, sliding, and uplift). MASTODON's capability to simulate nonlinear seism...
