Model Parameters of a Single Element
Model
The building's hybrid construction utilizes a mass timber structure including tapered glulam columns and beams, as well as steel elements such as the king post, tension rods, and strengthening elements hidden in the roof above the main structure.
The entire roof structure consists of repetitive individual structures resembling pear blossoms. Together, these blossom elements form a perfectly shaped architectural unit. Each of the individual structures is supported on 5 columns with a height of 16 to 23 ft.
The bottom of each column is fixed with steel parts and glued-in rods are employed to make the connection possible. Glued-in rods are also used for the moment connections at the Y-shaped joint of the roof frame. The RFEM structural analysis program was used to fully model the structure, confirm member sizes, and determine the forces for the connection design. In addition, the RF-STABILITY add-on module was further used to calculate the overall buckling analysis for the flower structure and the local buckling analysis for the king post.
The engineering firm JKA, located in Vancouver, Canada, provided the full mass timber consulting services, from preliminary design to the critical connection design. JKA are mass timber experts providing their clients with solutions of Integrity, Simplicity, Beauty.

Generation of Snow Loads in RFEM 6 According to ASCE/SEI 7-16 and EN 1991-1-3
The effects due to snow load are described in the American standard ASCE/SEI 7-16 and in Eurocode 1, Parts 1 through 3. These standards are implemented in the new RFEM 6 program and the Snow Load Wizard, which serves to facilitate the application of snow loads. In addition to this, the most recent generation of the program allows the construction site to be specified on a digital map, thus allowing the snow load zone to be imported automatically. These data are, in turn, used by the Load Wizard to simulate the effects due to the snow load.

Steel Joints | Stability Analysis Software
For the components of the joint, you can check whether stability failure is relevant (add-on structural stability for RFEM 6/RSTAB 9 required).
The critical load factor for all analyzed load combinations and the selected number of mode shapes is calculated for the connection model. The smallest critical load factor is compared with the limit value 15 from the standard EN 1993-1-1, clause 5. In addition, a user-defined adjustment of the limit value is possible. Furthermore, the corresponding mode shapes are displayed graphically as the result of the stability analysis.
For the stability analysis, an adapted surface model is used to specifically recognize the local buckling shapes. The model of the stability analysis, including the results, can also be saved and used as a separate model file.
- Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- How can I optimize cross-sections within the steel design?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- How do I apply wind load on members of open structures?
- Is it also possible to use RF‑/TOWER Loading without the other TOWER add-on modules?
- I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
- 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?
- I encountered a sharing violation while importing a dxf file into SHAPE-THIN. What is the issue?
