Forell Elsesser is providing structural engineering services for UC Berkeley’s new Undergraduate Academic Building (UAB). This 78,000 square-foot, L-shaped, 5-story facility will serve the Mathematics and Economics Departments, offering a combination of general classrooms on the lower levels and office spaces above. The UAB represents a forward-thinking approach to both structural engineering and sustainability, marking UC Berkeley’s first mass timber construction project.
Customized Solution
- The building’s design incorporates a steel gravity and lateral system, with an auditorium that features 80-foot long-span steel trusses, seismically separated from the main structure. This not only enhances flexibility but also improves seismic resilience. The auditorium section, which includes an occupied green roof, physically connects the east and west wings of the UAB via exterior stairs, creating a functional and aesthetic link between the spaces.
- In alignment with UC Berkeley’s commitment to sustainability, UAB utilizes mass timber, significantly reducing the building’s carbon footprint. The structural system features glulam beams and columns, as well as 5-ply Cross Laminated Timber (CLT) diaphragms to efficiently resist both gravity and seismic loads. With much of the mass timber left exposed, the design creates a warm and natural aesthetic that extends from the interior to the exterior, further elevating the building’s architectural and environmental appeal.
- To ensure top-tier seismic performance, the project incorporates advanced nonlinear analysis, optimizing the lateral design for earthquake resilience. This performance-based approach allows us to predict the building’s behavior under seismic forces with a high degree of accuracy, providing enhanced safety and cost efficiency.
- The UAB project has successfully undergone peer review and received approval from the UC Berkeley Seismic Review Committee (SRC), ensuring compliance with the university’s stringent seismic standards. Forell Elsesser’s work on this project reflects our continued focus on integrating mass timber as a structural solution and applying advanced seismic analysis techniques to deliver safe, efficient, and sustainable buildings.
