Structural Engineering Software for Towers and Masts
In June 2018, a new and unique lookout tower by world-famous architect Martin Rajniš opened in the Prague municipal district of Kyje. When designing the tower, maximum emphasis was placed on the use of natural and renewable material.The lookout tower structure is constructed with acacia logs 3.15 inches in diameter. The main supporting structure includes three legs, where a spiral staircase is also suspended. The tower legs are made of a lattice structure in the shape of an elongated barrel. At the top, the legs are interconnected with three steel hoops and a triangular steel structure.The tower is 77.1 ft high with the observation platform located 65.5 feet above ground elevation. The observation tower can hold up to 9 people during typical operation.

Model
Structural Analysis
The RFEM model was initially created by importing the architectural model from AutoCAD. End releases were conservatively applied to all members even though many members overlap.
The RFEM calculation included a second-order analysis with the Picard method. For the design, a possible progressive collapse of the structure was taken into consideration where one of the highly loaded elements may fail (break). The model was also used to verify the various construction stages when installing the structure with cranes.

Saving Models as Blocks in RFEM 6
In RFEM 6 it is possible to save selected objects, as well as whole structures, as blocks and reuse them in other models. Three types of blocks can be distinguished: non-parameterized, parameterized, and dynamic blocks (via JavaScript). This article will focus on the first block type (non-parameterized).

Timber Design | Strength and Stability | Results
After the design, the performed design checks are displayed in a table. All result details can be displayed and retraced using the clearly arranged design formulas.
The design checks are carried out at all governing locations of the members and displayed graphically as a result diagram. Furthermore, there are the detailed graphics, such as the stress distribution on a cross-section or the governing mode shape, available in the result output.
All input and result data are part of the RFEM/RSTAB printout report. You can select the report contents and extent specifically for the individual designs.

How do I define a member as a cantilever and not as supported at both ends for serviceability or deflection design?
- I would like to export nodal support forces of several load cases, load combinations and result combinations into an Excel spreadsheet in RFEM 6. How should I proceed?
- Where can find the option to hide the defined types (for example, design supports or effective lengths)?
- How do I create a user-defined Design Situation with my own chosen load combinations?
- How can I neglect torsion in the steel and timber design?
