Model
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.
Project
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 at providing 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
Structure
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.

Modal Analysis in RFEM 6 Using a Practical Example
Modal analysis is the starting point for the dynamic analysis of structural systems. This article shows you a summary of how to perform a modal analysis in RFEM 6.

Timber Design | Strength and Stability | Results
After the design, the performed design checks are displayed in a table. All result details can be displayed and retraced using the clearly arranged design formulas.
The design checks are carried out at all governing locations of the members and displayed graphically as a result diagram. Furthermore, there are the detailed graphics, such as the stress distribution on a cross-section or the governing mode shape, available in the result output.
All input and result data are part of the RFEM/RSTAB printout report. You can select the report contents and extent specifically for the individual designs.

The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- In RFEM 6, is it possible to display a graphic with the distribution of the required reinforcement in the DIN A0 format?
- How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
- Where can I find the graphical results of punching shear in the concrete design? Especially the distribution of shear forces at the critical perimeter or the punching loads.
- Is it possible to display the reinforcement description in RFEM 6?
-
I would like to export nodal support forces of several load cases, load combinations and result combinations into an Excel spreadsheet in RFEM 6. How should I proceed?
- Where can find the option to hide the defined types (for example, design supports or effective lengths)?
- How do I create a user-defined Design Situation with my own chosen load combinations?
- How can I neglect torsion in the steel and timber design?
- Can I define a different bar size in the RFEM 6 Concrete Design add-on other than the default bar sizes available in the drop-down?
