Harzdrenalin Membrane Roof at Rappbode Dam in Harz Mountains, Germany
Customer Project
In 2022, the event area of the breathtaking "Harzdrenalin" attraction was given an elegant canvas roof made of three membranes. This lightweight structure is intended to protect visitors from sun and rain.

Gisela Zündel from the engineering office for structural design in Lorch, Germany, was responsible for the structural analysis and planning of the membrane roof. The FEA program RFEM and the RF-FORM-FINDING, RF-CUTTING, and RF-STEEL EC3 add-on modules were used.
Harzdrenalin - Attraction in the Harz Mountains
"Harzdrenalin" at the Rappbode Dam in Germany's Harz Mountains offers visitors several options to experience an adrenaline rush. The most harmless of the attractions is the Titan-RT suspension bridge, which is about 500 yards long. The Mega Zip Line for guests, soaring about 130 yards above the Rappbode Dam's precipice, requires a little more courage. And if that is not enough action, really brave guests can be catapulted for 125 ft into the air by a human catapult or dare to jump from the suspension bridge.
Membrane Structure
Three membranes are attached by cables to the straight column in the center and the inclined columns on the edges. All the columns consist of round pipes of steel grade S 355. The edge columns are cable-stayed, the guys being anchored in the ground. The central column, which is the tallest, is approximately 31 feet high. In total, the membrane structure covers an area of about 360 square yards.

The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- How can I efficiently define line hinges on several surfaces?
- How do I include the overstrength factor(s) Ωo in the ASCE 7 load combinations?
