Slabs Base Module of CEDRUS

The base module of CEDRUS is a program for the structural anlysis of slabs based on the finite element method. It is very user-friendly and designed especially for dimensioning reinforced concrete slabs of building constructions. Miscellaneous modules are availabe as add-ons for solving more specific problems like the prestressing module with which tendons can easily be defined and used.

Details on modeling

Outlines and openings with arbitrary shapes
Zones with different slab thickness, material model (isotropic, orthotropic, flexible for drilling) and material properties
Downstands as stand-alone objects
Columns with arbitrary shaped cross sections and supporting zones; automatically computed stiffness of vertical displacements
Point supports, line supports and area supports (foundation slabs) with any desired elasticity properties
Lines of symmetry
Support without tensile force transmissions for all types of supports
Joints with various characteristics such as hinge stiffnesses and separating lines

Loading types

Area loads with polygonally shaped boundaries applicable for handling dead weight, uniformly distributed loads and
temperature differences
Uniformly and trapezoidally distributed line loads and line moments of any type of shape
Point loads and point moments
Prescibed discplacements and rotations of supporting points
Influence fields for moments, deformations and reactions
Automized generation of unfavorable load patterns
Load assignments to actions according to codes (SIA, EC, DIN, OeNorm)

Finite elements / solving procedures

Arbitrarily shaped triangles and quadrangles with hybrid formulations; nodes with 3 degrees of freedom
Fully automized mesh generation incorpoarting global or zoneweise specifications of mesh density and principal directions
Fast solving procedures
Unlimitted number of elements

Results
of loadings and combinations of loadings

Section forces (moments and shear forces) zonewise in arbitrary directions
Principal moments, maximal shear forces
Deformations
Reactions, in case of line supports as mean values section by section
Automized export of the reactions in order to load underneath arranged slabs

of envelopes

Automatical superposition of loadings according to the selected code (actions, hazard scenarios/design situations)
Reinforcement moments zonewise in arbitrary directions, shear forces
Amount of reinforcements zonewise in arbitrary orthogonal directions, designed for ultimate state or permissible steel stresses
Deformations
Reactions, in case of line supports as mean values section by section
Punching shear check

Output format

The results can either be visualized graphically (isolines, 3D view, sections, princaple plots, reaction plots) or numerically
tabular formatted.
Evaluation of section forces and reinforcement results along beam sections (integrated values across the section width)
