"Dynamite" Big Dipper Coaster in Amusement Park Plohn, Germany
You can experience spectacular roller coaster rides on Germany's first Big Dipper Coaster (since May 2019). Since its opening, the approximately 131-foot-high and 547-yard-long coaster has been one of the main attractions in the Plohn amusement park in Vogtland, Saxony.

During the high-speed ride with speeds of up to 62.1 mph including looping, helix, and corkscrews, you can experience accelerations of 4.4 g and a feeling of weightlessness. In addition, you go through a dark tunnel and later, over it.
The Big Dipper means that only one vehicle drives and four people sit in two rows each. The outer seats are very far from the tracks, so you are floating next to the vehicle, so to speak.
Structural Analysis and Construction
Dlubal's customer Weiß Beratende Ingenieure performed the structural analysis of the roller coaster in RSTAB. For the fatigue calculation of the steel components, the internal forces were exported from RSTAB with the RS-COM interface and the fatigue designs were performed with a separate program. Weiß Beratende Ingenieure also calculated the station and the maintenance hall in RSTAB, as well as the tunnel, including the decoration house (timber structure) in RFEM.
The approximately 547-yard-long track of the Big Dipper forms a three-chord truss girder made of tubular steel sections. This truss girder is supported by a total of 76 columns. These are A-frames or fully restrained single columns. The roller coaster structure, made of S 355 steel, has a total weight of approximately 330.6 tons.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- I would like to calculate and design "temporary structures." What do I need for this?
- How is it possible to consider the real cross-section geometry of member elements in RWIND Simulation?
- How is it possible to make factorized combinations of a dead load in the context of form‑finding?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- The design ratio of the cross-section check is different for the RF‑/STEEL and RF‑/STEEL EC3 add-on module. What is the reason?
- What is the meaning of the warning message ER061) Minimum amplifier of design loads <1?
- How can I optimize the calculation time in CRANEWAY?
- I would like to define lateral supports along the axis of a structural component that sometimes act on the upper flange, sometimes on the lower flange. However, it is only possible to select one item for each member. How can I create the entry?
- Is it possible to divide a free surface load by the existing lines in RFEM?
- I design a cross-section created in the SHAPE‑THIN program by using the design add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
