FEM-Design Plate
With FEM-Design Plate, concrete slabs or other
two-dimensional transversely loaded structures can be
analysed.
Reinforced concrete is designed according to code,
accounting for cracked section analysis, shrinkage and
creep considering calculated or applied reinforcement.
Required reinforcement is calculated for ultimate or
serviceability limit state, checking defl ections and/or
crack width. Alternatively, reinforcement can be applied
and checked according to code and defl ections and crack
patterns displayed.
FEM-Design Wall
The Wall module offers design solutions for plane stress
problems, such as shear and load bearing walls as well
as for other kinds of structural elements such as webs of
deep beams or steel plates.
Concrete walls are designed according to EC2 and different
national codes. Design forces are calculated as a
combination of normal and shear stresses in the wall.
Tension reinforcement requirements are calculated and a
check is made that allowable compressive stresses in the
concrete are not exceeded.
PreDesign
The FEM-Design PreDesign module is used tp perform
a pre-calculation for reaction and internal forces of load
bearing walls and columns and to estimate material
quantities for the entire structure.
Automatic wind, snow and deviation load generation
ensure fast and easy defi nition of the complete statical
model which later can be opened in 3D Structure for indepth
analysis and design.

FEM-Design 3D Structure
FEM-Design 3D Structure is an analysis and design software
for complete structures containing a combination
of shell elements, slabs, walls, bars, beams and columns
with arbitrary loads.
The steel and concrete modules allow code-specifi c
design of all elements in the entire 3D-model.
Static-, dynamic- and seismic analysis can be performed
as well as solving global stability problems.
Simple & user-friendly working environment
Intelligent data connections via DXF, DWG and IFC
as well as direct links from Tekla ® and Revit ® Structure
Wizard for quick and easy input of slab and frame
systems
Point, line and surface supports with rigid, free or
elastic stiffness components
Relative constraints
Section editor for defi ning sections for bars, beams
and columns with arbitrary shapes
Automatic generation of most unfavourable load
combinations according to standards
A powerful automatic optimal fi nite element mesh
generator for any geometry
No limit to the number of fi nite elements
Peak smoothing
Animation of displacement, vibration and stability
results
Analysis and steel design of straight bars with varying
cross sections and bars with hollow space and
stiffeners
Steel design according to 2 nd order theory and
imperfections
Powerful concrete design and reinforcement
checking
Model
The geometry is easily created in 3D with the use of intuitive
tools such as axis and storey-system, region operation,
user-defi ned views and user-coordinate-system.
Underlays of CAD-fi les can be inserted as DWG or DXF.
Complete 3D architectural or structural models can be
imported via IFC model-based interface or from the direct
links provided from Tekla ® and Revit ® Structure.
Arbitrary shapes of shell elements can be created using
solids and solid operations.
Relative constraints allow connections between structural
objects to be modelled accurately. This can be used for
analyzing connection forces between prefabricated elements.
As well as normal point, line and surface loads, temperature,
stress, and seismic loads can also be defi ned.
Analyse
Static, dynamic (eigen frequencies), stability and seismic
analysis can be carried out for the entire structure at
once.
The fi nite element mesh is automatically generated with
optimal element sizes and automatic refi nements at supports
and element connections, freeing the user to focus
on the engineering task. There is no limit to the number
of elements.
A number of display methods can be used for viewing
results including graphs, contour lines, colour palettes in
3D for the whole structure, in 2D for each wall or slab,
or as arbitrarily placed
sections.
Absolute or local maximum
and minimum
values can be displayed
automatically, or the
user can point anywhere
on the structure to get a
numeric result value.

Design
Steel design is carried out according to EC3 or several
national codes using the steel design module (see 3D-
Frame).
Steel bars can automatically be converted to shell elements,
allowing varying cross-sections, cut-outs and stiffeners,
and checked for buckling shapes and utilisation for
fl exural-, torsional-, lateral torsional- and local buckling.
The powerful concrete module designs according to EC2
or national codes accounting for shrinkage behaviour.
Reinforcement can be designed according to defl ection
and crack-width criteria as well as ultimate limit state
design.
Applied reinforcement in the concrete elements is
checked according to code, and accurate crack-width
and defl ection calculations can be made for specifi c reinforcement.

Documentation
One challenge of complex calculation projects is the
presentation and documentation of results, whether for
municipalities, clients or for archiving purposes.
FEM-Design offers an easy and elegant way to create
complete and conceivable documentation of projects
containing a cover page with title table, chapters,
fi gures, texts, tables, headers/footers, images and table
of contents.
Images are easily set up to display desired result, displaymode,
scales and text size and are automatically
refreshed when changes have been made to the model
or calculation.
Templates can be edited and stored in order to re-use
standard styles for other projects.
Results can also be exported to Microsoft ® Word and
Excel.
3D Frame
FEM-Design 3D-Frame is an analysis and design software
for three-dimensional frame and truss structures.
Common structures can be generated along with
loads in a few simple steps using the parametric input
wizard. In the Section Editor, complex arbitrary section
shapes (opened or closed) can be created for bars,
beams and columns. All sectional parameters are automatically
calculated for the current section.
Using relative constraints, connections or intersections
between elements can be modelled with ease. Eccentric
3D bars or semi-rigid connection of columns and
beams can be modelled in this way.
The analysis includes 2 nd order analysis, dynamic analysis
of eigenfrequencies and vibration modes, seismic
calculations according to response spectra, stability and
imperfection calculations.
With “soft spring” procedures, an automatic check of
insuffi cient supports and connections can be run to
solve instable structures.
Steel structures are designed according to EC3 or
national codes. Steel bars can be checked with regard
to 1 st or 2 nd order theory where imperfections are
automatically calculated by connecting the 2 nd order
analysis to one of the critical buckling modes. The design
is performed for stresses, fl exural buckling, lateral
torsional and torsional buckling, web buckling and
fl ange buckling.
Concrete design for 3D beams and columns is also
available for EC2 and national codes.
