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 includes not only living suites and pods primarily for sophomores, with a total of 708 beds, but also includes vibrant space for dining facilities, classrooms, administrative offices, faculty housing, and much more.
The series of interconnected buildings in serpentine configuration is 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 building’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 taken into consideration 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.

This article compares the design to the one in the referenced article: Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Members. It is, therefore, about taking exactly the same theoretical application carried out in RF-CONCRETE Members and reproducing it in RF-CONCRETE Columns. Thus, the objective is to compare the different input parameters and the results obtained by the two add-on modules for the design of column-like concrete members.

- I have a roof structure resting on a steel column that runs to the foundations. The column runs through a perimeter wall that supports the false ceiling. A considerable part of the load from the roof is transferred to the wall. I want the steel column to carry all the vertical loads from the roof. How can I do it?
- Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- How does the "Orthotropic Plastic" material model work in RFEM?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- Does the program check the lap length of the vertical stirrups of a block foundation with smooth bucket sides?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
- Is there a possibility in RFEM to define a global polar grid with the origin lies in the global zero point, for example, and which applies to several surfaces?
- When comparing RF‑CONCRETE Columns with another design software, I get different results. How to explain the differences?
