Why Ignore the Structure? Soil-structure Interaction and Site Response at Local and Regional Scales

In regions prone to seismic activity, the execution of reliable site response analyses stands out as a cost-efficient measure during the design phase of critical infrastructure such as buildings, rail and tunneling systems, and power plants and utility networks. The dynamic interactions between structural components and underlying soil layers, known as soil-structure interaction (SSI), impact the overall seismic performance and safety of  structures, and are relevant at both site-specific and regional scales.

In this session, we invite researchers and practitioners to contribute to a cohesive understanding of SSI and local site effects, two essential components of seismic design. This session seeks fostering of cutting-edge methodologies and innovative approaches in areas including but not limited to site response analysis (e.g., nonlinear 1D/3D site effects), kinematic and inertial effects of SSI (e.g., numerical and experimental modeling), and their effects on structures with deeply embedded foundations and large footprints (e.g., nuclear power plants). Additionally, we welcome studies investigating the role of physics-based simulations in improving our understanding of SRA and SSI, the complexities of SSI in urban and regional settings,  and risk assessments of portfolios of infrastructure assets such as densely built environments or pipeline networks.
