SHAPE-THIN | Calculation
SHAPE-THIN calculates all relevant cross‑section properties, including plastic limit forces and moments. Overlapping areas are set close to reality. If cross-sections consist of different materials, SHAPE‑THIN determines the effective cross‑section properties with respect to the reference material.
In addition to the elastic stress analysis, you can perform the plastic including interaction of internal forces for any cross‑section shape. The plastic interaction design is carried out according to the Simplex Method. You can select the yield hypothesis according to Tresca or von Mises.
It is possible to calculate the section properties and stresses of the effective cross-section according to EN 1993‑1‑1 and EN 1993‑1‑5 or EN 1999‑1‑1. Cross‑section classification considers the available combination of internal forces.
Optionally, SHAPE‑THIN checks the limit values (c/t) in compliance with the design methods el‑el, el‑pl or pl‑pl according to DIN 18800. The (c/t) zones of elements connected in the same direction are recognized automatically.
