Steel Hall with Flat-Shaped Duopitch Roof
Model to Download
Using the load generator, wind loads can be applied to duopitch roofs and flat roofs. The special case of a flat-shaped duopitch roof smaller than 5 degrees is recognized by the load generator of duopitch roof shapes. In this situation, the generator applies a load diagram for an equivalent flat roof.
This model was used to demonstrate it.
Model Used in
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.
