The plant, which manufactures railroad ties, required access over the Fanggraben river to the rail siding warehouse. The new railway bridge spans the Fanggraben river at an incline angle of 63 gradians (56.7°).
Due to the limited distance between the top of rail to the top of the water height, the bridge’s supporting structure required a minimal depth. A steel half-through bridge design constructed with a thick sheet metal deck without supporting transverse beams was selected.
The bridge dimensions include a 42 ft length, 37 ft span, and 16 ft clear width. The engineering office Schröder + Raue from Zwickau utilized the finite element program RFEM to analyze and design the structure.

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.
