A timber lookout tower called "Ester" opened in Jerusalem in mid-November 2017. This tower, in the shape of a blooming cactus, was designed by renowned Czech architect Martin Rajniš and is located in the complex of a former hospital from 1887, not far from the Old Town walls. It offers visitors a spectacular view over Jerusalem.
All timber, steel, and membrane elements were prefabricated in the Czech Republic and then loaded into two 39.37-foot-long containers. All components were manufactured to a high quality, both manually and using CNC technology. This quality standard was an essential prerequisite for the successful and quick assembly in Israel.
All the prefabricated components were assembled in a horizontal position, including the spiral stairway inside the wooden supporting cuboid.

After generating the effective lengths, the results are displayed in clearly arranged tables. You can modify the effective lengths manually there.
The Export function transfers the effective lengths to the RF-/TOWER Design add-on module for further calculation. The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
Finally, it is possible to export the generated model to RFEM/RSTAB with a single mouse click.
The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
The results are displayed in clearly arranged module windows. In addition to the design data, the results include all design-relevant parameters. A parts list is generated automatically during the calculation.
The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
When performing the design of tension, compression, bending, and shear loading, the module compares the design values of the maximum load capacity to the design values of the actions. If the components are subjected to both bending and compression, the program performs an interaction. You can determine the factors according to Method 1 (Annex A) or Method 2 (Annex B).
The flexural buckling design requires neither the slenderness nor the elastic critical buckling load of the governing buckling case. The module automatically calculates all required factors for the bending stress design value. RF-/TOWER Design determines the effective critical moment for lateral-torsional buckling for each member on every x-location of the cross-section.
