GRAITEC Advance Design: New method of load distribution from Load areas
Advance Design uses Load Areas to transfer loads from surfaces such as roofing and walling to the supporting linear element. Previously, the load distribution from load area to linear elements was conducted solely according to failure lines theory. Despite its practicality, this approach is mostly accurate for quadrilateral load area with uniform load distribution all over it. In such cases, we get the classic analytical envelope load distribution. However, when dealing with a more complex load system and more complex load area geometry, the analytical method is not able to represent the actual distribution of forces on the bars, as the inaccuracy of the failure line theory increases.
In the latest version of Advance Design 2025, to cover all loading scenarios with good precision, an additional new finite element load distribution algorithm has been introduced. The new 23 What's New in Advance Design 2025 algorithm can be activated individually for Load area, and for this purpose in its parameters appeared a field with a choice of three options: Failure lines, FEM transfer and Auto.
