Model
This one-story house, made of cross-laminated and glued laminated timber, will be awarded a prestigious certification for passive houses, a symbol of high quality standards in terms of energy efficiency and CO2 consumption.
Structure and Design
The house has an irregular floor plan and is based on a reinforced concrete floor slab. The wall and roof structures are made of cross-laminated timber. The roof structure is reinforced with class GL24h glulam beams to define a special inverted roof with sharp cantilevers standing out of the façade. In order to achieve high spans, the timber beams had to be reinforced with steel beams in some locations of the roof.
The RFEM finite element program was used to simulate the structural behavior of the entire system, including line hinges between the cross-laminated timber panels and the elastic foundation under the floor slab. The design according to the standard was performed with the add-on modules RF-LAMINATE and RF-CONCRETE Surfaces in order to optimize the thicknesses.
It was necessary to create a local model to evaluate the connection between the steel and timber beams on the cantilevers and to analyze the resistance of the fasteners (pulling out) under specific situations, such as wind pressure and suction.

X-Brace Effective Lengths According to AISC 360-16 in RFEM 6
Defining the appropriate effective length is crucial to obtain the correct member design capacity. For X-bracing that is connected at the center, the engineers often wonder if the full end-to-end length of the member shall be used or using half of the length to where the members are connected is sufficient.
This article outlines the recommendations given by the AISC and provides an example on how to specify the effective length of the X-braces in RFEM.

Steel Joints | Stability Analysis Software
For the joint components, it is possible to check whether the stability failure is relevant (requires the Structure Stability add-on for RFEM 6 / RSTAB 9).
In this case, 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. Furthermore, a user-defined adjustment of the limit value is possible. Moreover, 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.
- 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?
- Can the RFEM 6 Concrete Design add-on automatically design member and surface reinforcement?
- Why is it not possible to select the user-defined additional reinforcement for the serviceability limit state design in RF‑CONCRETE Surfaces?
- What is the maximum number of reinforcement groups that can be created in a design case in RF‑CONCRETE Surfaces?
- I would like to perform punching design of a floor slab. I have selected nodes for the design, but they are marked as invalid. Where did I make a mistake?
- Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
- Is the deformation analysis in state II included in the concrete design in RFEM 6?
- How can I open the interaction diagram from Concrete Design?
- Why are the members not valid for the Concrete Design add-on?
