Heinz Bornemann, a customer of Dlubal Software, provides structural analysis and design for a wide range of this playground equipment; for example, the "Globe" and various types of "Tetragode". RSTAB structural frame analysis software is used for the calculation of spatial supporting structures.
Globe
The outer frame of the Globe play structure consists of eight curved glued-laminated beams of 4 23⁄32 inches / 9 29⁄64 inches. The three-dimensional inner net includes "U-Rope" ropes developed by Berlin Seilfabrik. The outer dimensions (L x W x H) are approximately 14.8 ft x 14.8 ft x 16.4 ft. The analysis was performed in the add-on modules TIMBER Pro and STEEL.Tetragode
Tetragode is a central mast play structure. A number of children can climb to great heights simultaneously. This type of Tetragode is about 21.3 ft high. The spatial rope net also consists of U-Ropes by Berliner Seilfabrik and extends outwards from the central steel mast in four directions.
