1.1 Program requirements

Application requires .NET Framework 4.5 to be installed on the computer. It can be
downloaded from web pages of Microsoft Company (https://www.microsoft.com/en-
US/download/details.aspx?id=30653).
In case of a missing .NET Framework the installation is not launched.
1.2 Installation guidelines

IDEA CSS program is installed as a part of IDEA StatiCa package.

2 Basic Terms
IDEA CSS is a program for input of general cross-section, analysis of cross-section
characteristics and analysis of stresses caused by defined internal forces. IDEA CSS is one
from the group of programs developed by IDEA RS company, especially for 2D FEA
structural analysis. All these programs work with the same data model. This allows their
direct connection with all IDEA design modules.
It is possible to input cross-sections of general shape, which consist of one or more
components. Cross-section characteristics and courses of stresses caused by unit loads are
calculated for defined cross-sections.
It is possible to input design matrixes. Each design matrix can contain one or more sextuplets
of internal forces.
Design matrixes and cross-sections can be combined into check requirements. Stresses are
calculated for defined check requirements.
The program general cross-section can be used as plugin to define general cross-sections in
modules IDEA Beam, IDEA Frame and .

3 User interface
The items of user interface of the application are composed into following groups:
 Navigator – it contains main commands for the work with a project
 Ribbons – there are sets of controls. Ribbons are changed according to the current
command on Navigator.
 Main window – it is used mainly for appropriate drawings
 Data window – properties of objects and results of analysis are displayed in this
window according to current command of Navigator
All other IDEA applications have the similar design.

5.2.1 Components of general cross-section

The general cross-section geometry contains components of cross-section.
Components of cross-section can be defined:
 Selecting a component shape from the database of concrete cross-sections;
 Selecting a component shape from the database of steel cross-sections;
 Importing the shape from DXF file;
 Defining the shape using a table editor.
Each cross-section component has a local coordinate system. The local coordinate system of
the component is placed to the origin of global coordinate system by default.
If the cross-section component depends on some master component, the local coordinate
system of slave component is placed to the Master point of the Master component.
Each cross-section component has an Insert point. The Insert point is coincident with the
origin of local coordinate system of the component. When the Insert point is changed, the
component moves to keep the new Insert point in the origin of local coordinate system.
The Insert point of first cross-section component is placed to the origin of global coordinate
system of the cross-section.
The Insert grid is generated for each cross-section component. This grid contains points in
important points of the cross-section. The Insert point can be set to any of point of the Insert
grid.
Dependencies can be defined between components of cross-section. One component can be
set as a master component for another component. The dependency is defined by two points.
A Master point, which is one of the points of the insert grid of the master component, is set
for the dependent component. Than the dependent component moves to keep coincident the
Insert point of the dependent component with the Master point on the master component..

the point.
 Section – is defined by the point coordinates and by the slope of the line in this point.
Following values are taken from the section when calculating the stresses:
o The unit axial stress is taken in the section point.
o The unit shear stress caused by torsion is taken as the maximal shear stress
value along the whole section.
o The unit shear stress caused by shear force is taken as the average shear stress
value along the whole section.
For the sections from database the points for stress calculation are generated automatically in
important points of the cross-section. Stress points have to be added for cross-sections of
general shape.
The position of point for stress calculation is related to the defined cross-section component
and the master point on this component.
If there are no points for stress calculation on the cross-section, stress check cannot be
