Lipno Tree Tower, Czech Republic
Customer Project
In summer 2012, the first Czech treetop walkway opened in Lipno in the presence of Václav Klaus, then President of the Czech Republic. A path 2,214 ft in length leads to a major tourist attraction: the tree tower.On the top platform, at a height of 131 ft, visitors can enjoy the wonderful view from the wooden lookout over Šumava National Park and Lipno Dam on the Vltava River. In the center, the tower includes a playground slide 170.6 ft in length, representing the longest closed slide in the Czech Republic.

Model
Tree Tower
The tower construction consists of an external circular ring based on nine glued-laminated timber columns which have been arranged in rotational symmetry and set up with an angle difference of 40° each, thus forming a polygonal, spatial structure.
A steel pylon made of a round pipe was built inside the tower. Steel spiral stairs with steel grids and a tunnel slide are attached to the pylon, which is connected to the tower at two height levels: at 78.7 ft and 131.2 ft.
Visitors have access to the tower using the treetop walkway, ending at 78.7 ft above the ground, or climbing the spiral staircase. From there, they can reach the viewing platform by climbing a spiral timber construction that is attached to the timber columns by means of cantilevered steel beams.
The construction has been stiffened by a close mesh of diagonal steel members anchored in the timber columns. Furthermore, four horizontal ring constructions consisting of steel pipes have been arranged in the lower part of the tower.

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 | Result Filter by Limit State
The design checks are available in a tabular form in the Timber Design add-on. The distribution of the design ratios can also be displayed graphically. There are extensive filter options available in the table as well as in the graphical output to display the desired design checks by a limit state or a design type.

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?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
