How was RISA used?
The Hannahville Indian Community facility required a robust framework to support its half-circle form, floating walkway, and curved steel roofs. Multiple RISA tools streamlined design, improved efficiency, and ensured long-term resilience. RISAFloor and RISA-3D guided gravity and lateral design of steel framing, braced frames, and masonry shear walls, with semi-rigid diaphragms capturing wind effects across the curved geometry. RISAFoundation optimized the concrete foundation system, while RISAConnection addressed skewed geometries and custom bearing conditions. RISA-3D also analyzed load paths and dynamic behavior of the roof and walkway, confirming performance under both aesthetic and environmental demands. Together, RISA’s suite delivered a cohesive, cost-effective solution that aligned cultural intent with structural integrity.
RISA gives back
To recognize the hard work and dedication on the Hannahville Indian
Community Governmental & Health Services Building,
RISA will be donating $500 to the DSID.
Founded in 1969, the Delta-Schoolcraft Intermediate School District Learning Center provides specialized education for students ages 3 to 26 with moderate to severe impairments. Through collaboration among families, educators, and the community, the center creates programs that foster learning, growth, and inclusion beyond the traditional classroom setting.
