Model Parameters of a Single Element
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.

In this article, the adequacy of a 2x4 dimension lumber subject to combined bi-axial bending and axial compression is verified using RF-/TIMBER AWC add-on module. The beam-column properties and loading are based on example E1.8 of AWC Structural Wood Design Examples 2015/2018.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- I design a cross-section created in the SHAPE‑THIN program by using the design add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
- Can I use RFEM to calculate a log house three-dimensionally?
- In RF‑/STEEL EC3, I get an error message saying that the node with a support does not exist in the set of members. What is the reason?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Is it also possible to subsequently deactivate the symbols for the FE mesh refinement in an existing graphic in a printout report?
- What is the difference between SHAPE‑THIN 9 and SHAPE‑THIN 8?
- SHAPE‑THIN calculates a very small shear area. Why?
- 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?
- When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears saying that the value is out of the valid range (existing value: 108, minimum value 100, maximum value 100). What does this message mean?
