Collegium Academicum - Dormitory in Heidelberg, Germany
On the site of the former US hospital in Heidelberg-Rohrbach, a dormitory is being constructed that will be both a residence and a meeting place for students, trainees, and young professionals from the Collegium Academicum.

Cross-Laminated Timber Floor Model Parameters
This project focuses on sustainability and innovation. Cross-laminated timber, glued laminated timber, and BauBuche are primarily used as the building materials.
The structure offers space for 176 residents in 46 apartments. The total cost of the project amounts to 18 million euros. Dlubal customer PIRMIN JUNG was responsible for the structural design as well as the room and architectural acoustics. They utilized the RFEM and RSTAB programs for the structural analysis.
The Collegium Academicum dormitory consists of three structures connected by a single-story hall. The timber structure is joined by form-fitting and force-fitting all-timber connections. In order to decrease the join loads, a narrow construction grid was selected. The building’s lateral stiffness includes cross-laminated timber panels for the walls and ceilings. The access balconies act as a projected frame structure. An additional unique feature of the project is that the partition walls within the residential units are movable and can be adjusted to individual needs.
The building, which is made mainly of renewable raw materials, is intended to offer young people in Heidelberg affordable long-term living space.

Compared to the RF‑/TIMBER Pro add-on module (RFEM 5 / RSTAB 8), the following new features have been added to the Timber Design add-on for RFEM 6 / RSTAB 9:
- In addition to Eurocode 5, other international standards are integrated (SIA 265, ANSI/AWC NDS, CSA 086, GB 50005)
- Design of compression perpendicular to grain (support pressure)
- Implementation of eigenvalue solver for determining the critical moment for lateral-torsional buckling (EC 5 only)
- Definition of different effective lengths for design at normal temperature and fire resistance design
- Evaluation of stresses via unit stresses (FEA)
- Optimized stability analyses for tapered members
- Unification of the materials for all national annexes (only one "EN" standard is now available in the material library for a better overview)
- Display of cross-section weakenings directly in the rendering
- Output of the used design check formulas (including a reference to the used equation from the standard)
- How can I neglect torsion in the steel and timber design?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- 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??
- Can I use RFEM to calculate a log house three-dimensionally?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- I would like to carry out the flexural buckling design for timber components with imperfections and internal forces according to the second-order analysis. Is it sufficient to activate this in Details of the RF‑/TIMBER Pro add-on module or is it necessary to make additional settings?
- Can I design laminated veneer lumber with RFEM/RSTAB?
- How can I calculate a timber-concrete composite floor with cross-laminated timber?
