SHAPE‑THIN cross‑section properties software determines the effective section properties of thin‑walled cross‑sections according to Eurocode 3 and Eurocode 9. Alternatively, the program allows plastic design of general cross‑sections according to the Simplex Method. In this process, plastic cross-section reserves are iteratively calculated for elastically determined internal forces. The following example describes the effective cross-section properties in the notching area of a rolled I-section. Afterwards, the results are compared with the plastic analysis.
In RF-/DYNAM Pro - Forced Vibrations, you can define time diagrams directly as functions in an edit field. The parameter t is reserved for the time steps, but apart from that, all parameters as defined in the "Edit Parameter" dialog can be used in RF‑/DYNAM Pro.
