The relatively new sport of “Topgolf,” originally from the United States, is rapidly gaining popularity across Europe. In response to this growing demand, a new Topgolf facility has been constructed in Vienna. The complex consists of a main building from which players hit golf balls toward a symmetrical, nearly parabolic playing field.
The playing field is enclosed by a net structure up to 55 metres high, designed to catch the golf balls. The net is supported by tall pylons and spans eleven fields with varying widths, depending on the axis. The plastic net is connected to the pylons via horizontal cables and a cable connection that incorporates a built-in predetermined breaking point. The size of each net segment is defined by the distance between pylons and the spacing of the horizontal cables.
Vertically, the net is suspended and stabilized using an upper load-bearing cable and additional vertical cables. At ground level, the net is anchored by a strip foundation.
The pylons are braced to the rear by a truss structure. Both the pylons and truss elements are constructed using circular hollow sections. Additional cable bracing is installed at the heights of the two truss connection points: the upper pair of cables span to the next axis, while the lower pair span toward a central support located between the axes. Two additional diagonal cables extend from the central truss node toward this support to enhance the buckling resistance of the overall structure.
