Hobro Arrest Prison Scaffolding, Denmark
The scaffolding structure consists of aluminum trusses with heights varying between 1.64 ft and 3.28 ft as well as horizontal steel beams, columns, railings and bracings. All elements are based on the PlusEight system.

This structure is designed as a facade scaffolding but can also serve as a weather protection roof as well as a multi-platform structure. The weather protection roof was modeled independently while the roof loads were applied to the scaffolding structure. The scaffolding is anchored to the masonry at numerous locations. This connection further transfers the wind loads to the building.
To finalize this project, multiple RFEM features were utilized such as nonlinear member end hinges and nodal supports. Furthermore, the RF-STEEL EC3 and RF-ALUMINUM add-on modules were utilized to design the structure according to EC 3 and EC 9. The designs were carried out according to the National Annex of Sweden.

The RF-/STEEL EC3 add-on module automatically transfers the buckling line to be used for the flexural buckling analysis for a cross-section from the cross-section properties. In particular for general cross -sections, but also for special cases, the assignment of the buckling line can be adjusted manually in the module input.

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.
