Adohi Hall, which means “woods” in Cherokee, located at the University of Arkansas (U of A) is the first university housing and mixed-use structure of its kind.
Completed in 2019, the project is currently the largest cross-laminated timber (CLT) building in the United States. Setting precedence among universities, the U of A is the first to complete a large-scale mass timber residence hall and living learning setting.
The series of interconnected buildings not only includes living suites and pods primarily for sophomore students with a total of 708 beds, but also includes vibrant space for retail dining, classrooms, administrative office, faculty housing, and much more.
The series of interconnected buildings in serpentine configuration aimed to provide additional communal outdoor spaces in contrast to traditional campus housing. Additionally, the structure’s advanced timber technologies with the use of CLT panels and glulam members, was an important sustainability proposal to significantly reduce the buidling’s carbon footprint.
The project has won numerous awards to date including:
- AIA St Louis Design Award 2019, Unbuilt Category: Distinguished Award
- Wood Design & Building Honor Award, 2020
- WoodWorks Multi-Family Wood Design Award, 2020
The engineers of Equilibrium Consulting Inc. modeled, analyzed and designed the main components of the building using RFEM. For the lateral wind analysis, the three wings of the building were considered independently. The individual wings are composed of reinforced concrete cores to which glulam beams and columns are connected.
As a joint collaboration between Equilibirum Consulting Inc. and the Austrian company binderholz Group, the CLT floors and CLT post-and-beam configurations were designed. The glulam beams, columns, and trusses were analyzed individually as simply supported elements. The engineers of Equlibrium utilized RFEM’s add-on modules RF- TIMBER AWC and RF-LAMINATE for the design according to the AWC/NDS standard.
The steel hangers for the glulam beam-to-column connections were analyzed using the beam on elastic foundation approach. The screws were idealized with linear elastic spring elements.
