Advanced Soil-Structure Interaction Services
NYA provides expert Soil-Structure Interaction (SSI) services for critical infrastructure and complex building systems. By understanding the interaction between soil behavior and structural response, our engineers deliver safer, more resilient designs. We evaluate settlement, stiffness, and seismic response to optimize foundation performance.
Why Soil-Structure Interaction Matters
Soil-Structure Interaction plays a vital role in accurate modeling and performance-based seismic design. For example, in areas with soft soils or high seismic activity, SSI analysis improves safety and reduces construction risks. Additionally, our integrated approach accounts for ground motion amplification and foundation damping.
Our Expertise in SSI Design
NYA’s team applies nonlinear time-history analysis, site-specific geotechnical data, and finite element modeling to understand real-world interaction. Moreover, we use state-of-the-art tools to assess foundation-structure compatibility. This enables cost-effective solutions for high-rise buildings, bridges, and critical facilities.
Soil-Structure Interaction Projects
Our SSI expertise has supported the design of projects across Los Angeles, San Francisco, and internationally. From seismic retrofits to new construction, we work closely with geotechnical consultants, architects, and city reviewers to deliver technically sound designs.

Soil-Structure Interaction (SSI)
NYA is redefining how high-rise structures interact with the ground beneath them.
Our pioneering framework for performance-based Soil-Structure Interaction (SSI) has been recognized by the 2025 SEAOC Convention,
where it will be formally presented as a benchmark for next-generation seismic analysis.
Our work, led by global leaders in SSI such as George Gazettas, is already drawing attention from visionary developments across the globe.
It is a clear signal that NYA is not just contributing to the future of SSI, we are helping lead it.
