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 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
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.

Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Columns
This article compares the design with the one in the following 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.
Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- 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 whose origin lies, for example, in the global zero point and which applies to several surfaces?
- When comparing RF‑CONCRETE Columns with another design software, I get different results. How to explain the differences?
- Is it possible to perform design without an additional reinforcement in RF‑CONCRETE Surfaces?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
-
I have installed Halfen HDB 13.60 on my PC. The version does not seem to be compatible with RF-PUNCH Pro anymore. The interface does not work. I am using version 5.26.02 of RFEM.
- When solving a foundation slab under a circular tank, I do not see the contact stress in the middle of the surface. What could be the reason for this?
-
The design criterion for VEd/VRd,c is displayed as governing, although there should be a shear reinforcement designed. Also, the design of VEd/VRds is missing. Why is that?
- Which calculation method is the basis for the stability analysis in RF‑CONCRETE Columns?
