Konrad Rodacki, a student of civil engineering at the Cracow University of Technology, used the RFEM program when writing his master's thesis. The subject of the thesis is the structural and dynamic analysis of the timber and steel dome of the Las Arena building in Barcelona, Spain.
A model was made in RFEM, consisting of 1,145 members. The entire structure was loaded with tangential forces due to wind and snow, and designed for the cross-sectional forces obtained in this way. The real stiffnesses of nodes were determined and the changes of forces and displacements were analyzed after taking into account the stiffnesses entered into the program.

Knowledge Base
You can define built-up timber cross-sections, for example, channel, T, I, and box girders. Single elements are connected by rigid or semi‑rigid connections. Furthermore, hybrid cross-sections are available. In this case, a submenu provides an option to assign different materials to the individual cross‑section parts.
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.
