The Dlubal program PLATE-BUCKLING is used to perform plate
buckling analyses for rectangular plates according to the
following standards:
EN 1993-1-5:2006
DIN 18800-3:1990-11
You can apply horizontal or vertical stiffeners to the plates
(for example flat plates, angles, T-stiffeners, trapezoidal
stiffeners, C-sections). Loading on the plate boundaries can
be applied in several ways. It is also possible to import them
from RSTAB/RFEM.
The plate buckling design in PLATE-BUCKLING always takes into
account the total buckling panel because in this way
stiffeners that may be available are considered in the 3D FE
model. Thus, designs for single (c/t) parts or buckling panel
sections are omitted.
Features :
- The following national annexes (NAs) are available for the
design according to Eurocode 3:
DIN EN1993-1-5/NA:2010-12 (Germany)
CSN EN1993-1-5/NA:2008-07 (Czech Republic)
UNI EN1993-1-5/NA:2011-02 (Italy)
NBN EN 1993-1-5/NA:2011-03 (Belgium)
- In addition to the NAs listed above, you can specify
user-defined NAs with your own factors.
- Import of all relevant internal forces from RSTAB/RFEM by
selecting numbers of members and buckling panels with
determination of governing boundary stresses
- Summary of stresses in load cases with determination of
governing load
- Separate materials can be set for stiffener and plate
- Import of stiffeners from comprehensive library (flat plate
and bulb flat steel, angle, T-, C- and trapezoidal stiffener)
- Determination of effective widths according to EN 1993-1-5
(table 4.1 or 4.2) or DIN 18800 part 3 eq. (4
- Optional calculation of critical local buckling stresses by
analytical formulas of annexes A.1, A.2, A.3 of EC 3 or by
means of FEA calculation
- Designs (stress, deformation, torsional buckling) of
longitudinal and transverse stiffeners
