SwRI: Structural Engineering, Center for Nuclear Waste Regulatory Analysis


	Finite element modeling of drip shield and waste package

Engineers at Southwest Research Institute (SwRI) conduct a variety of structural analyses encompassing civil and mechanical structures and offer solutions in the following specialized areas:

Seismic analysis of steel and reinforced concrete structures
- Soil-structure interaction analysis
- Nonlinear dynamic time history analysis
- Evaluation of seismic performance
- Development of fragility curves for different limit states
- Nonlinear static (pushover) analysis
Study of impact analysis of reinforced concrete walls
Evaluation of coupled mechanisms in nuclear-waste containers (e.g., effect of stress corrosion cracking on mechanical failure of the system)
Studies of nonlinear mechanical interaction between different alloy materials


SwRI engineers study the impact of a simulated aircraft crash on reinforced concrete shear wall.


SwRI conducts seismic fragility assessments of structural and mechanical systems for nuclear facilities to assess seismic risk. This figure shows fragility of a reinforced concrete shear wall.
