Critical Structures & Facilities

SI is an expert in evaluating critical structures and facilities for normal operating loads and extreme events. Some of the largest utilities and engineering companies in the world have looked to SI for seismic and advanced structural analysis solutions including root cause analysis, equipment qualifications, non-linear steel and concrete modeling, material aging and degradation, dynamic and non-linear seismic analysis, soil-structure interaction, and equipment/structure fragility analysis. Our capabilities include the use of explicit software programs that model load drops, tornado missile impacts, fluid-structure interaction, barrier design, shock propagation and isolation system design, and blast protective design. Our services are unique in that we provide seismic qualification of equipment through both analysis and shake table testing.
