Seismic Expertise for Critical Infrastructure, Complex Facilities, and High-Consequence Assets
Structural Integrity Associates (SIA) helps owners, operators, and design teams understand seismic demands, evaluate facility and component response, and develop technically sound solutions.
Our approach connects seismic demand definition with practical evaluation of how these assets perform during and after an earthquake. Engineers integrate ground motion characterization, site response, soil-structure interaction, structural dynamics, nonlinear response, equipment qualification, and risk-informed decision-making to identify vulnerabilities and develop targeted mitigation that supports safety, reliability, regulatory objectives, operational continuity, and long-term performance.
Structural Integrity Associates’ earthquake engineering work supports the full path from seismic hazard definition through facility and component response. Our engineers help clients establish technically sound design criteria, evaluate ground motion inputs, model dynamic behavior, and identify vulnerabilities that may affect safety, licensing, availability, or continued operation.
Seismic decisions are most effective when they are grounded in both engineering rigor and practical risk insight. SIA supports seismic fragility evaluations, risk assessments, retrofit prioritization, and design strategy development, helping clients understand risk, compare options, and make informed decisions about mitigation, upgrades, and long-term asset management.
For complex facilities and high-consequence assets, seismic response often depends on the interaction between structures, soil, equipment, fluids, and adjacent systems. Structural Integrity Associates applies advanced analytical methods and deep seismic experience to evaluate soil-structure interaction, structure-soil-structure interaction, seismic fluid-structure interaction, nonlinear behavior, and dynamic response under demanding loading conditions.
