PLII+ | Buckling Analysis | Update Information
Missing heading "equivalent stress"
Option for analytical buckling member behavior.
Errors in the result graph of the stresses according to DIN 18800 (Patch 7).
User interface issues fixed. The calculation results are not affected.
Buckling stiffeners updated in manual.
User interface: Better result synrchonization for "traffic light" preview.
Output: Cleanup of empty nodes in the document structure.
Internally some minor changes have been introduced in order to improve the overall program runtime stability.
Prior to switching to any of the predefined examples the "Save as ..." dialog is now shown. The waring and error messages related to trapezoidal stiffeners have been given more precise formulations.
Correction of stiffener properties
An underestimation of the stiffener properties lead to a slight overestimation of the imperfection coefficients.
New: Stiffener checks
The program has been extended by design checks for the stiffeners (not DIN 18800). Stiffeners are checked automatically, wereas the stiffener forces are taken from the numerical analysis of the plate. The output document contains a result summary for the design checks. In case more details results are of interest, model data and load data can be exported to the BTII programm.
PLii+ is a complete remake of the established PLii program. It not only implement the analysis of plate buckling according to EN 1993-1-5 sec. 10 (reduced stress approach), but offers the investigation of a plurality of loading cases in one single project and a generalised load definition. The new completely interactive 3d grafic view (editable load and dimension lables, model manipulation via context menus) allows easy handling driven by intuition.
