Program Concrete Fire

The software "Concrete Fire" verifies fire resistance of reinforced concrete cross-sections according to EN 1992-1-2.

User interface

The user interface consists of a main menu with toolbars in the upper part of the window, tree menu on the left and input/display part on the right side of the window. The main menu contains all tools and functions, which can be used during the work. The tree menu is used for the administration of individual project tasks as well as for switching between parts of an input. The work with the tree menu is described in the chapter "Tree menu". The tree menu can be alternated by the part "Data" of the main menu. Tools for documents printing are organized in the window "Print and export document", which can be opened using the printing icon in the toolbar "Files" or using the appropriate link in the part "File" of the main menu.

Two types of particular tasks can be used in the software:


  • Fast analysis of RC cross-section with unlimited number of loads.


  • Analysis of the whole member with specified diagrams of internal forces. This type is suitable for the batch analysis in programs "Fin 2D" a "Fin 3D".

These tasks can be added with the help of the buttons "Add section" and "Add member" in the heading of the tree menu.

Main screen

Default screen of the software contains general data of the project (identification details, design standard).

Frame "General project data" shows data, that can be input in the window "General project data". The window can be opened by using the button "Edit". The entered data can be used in heading and footing of documents.

The design standard including national annex can be changed in the part "Standard". These settings are placed in the window "Standard selection", that can be launched by the button "Edit".

The part "Fire resistance parameters" contains an option for input of default value of fire resistance for all tasks of the project. The input can be done in the window "Fire resistance", that can be launched by using the button "Edit". The check box "Set required fire resistance for all tasks" sets the specified fire resistance also to all existing tasks in the project. The setting "Save as default" will set specified fire resistance as a default for all new projects.

Window "Fire resistance"

Part "Calculation options" contains settings that may influence the analysis:

Check bar spacing

  • The check of bar spacing is performed both for longitudinal and shear reinforcement. Verification is described in the part "Structural rules" of the theoretical help.

Check of detailing only informative

  • Structural rules (reinforcement area, bar spacing) are checked, however, they don't affect the final result "Pass/Fail". The member is considered as passed, even though some structural rules aren't fulfilled.

The setting "Use wizard for new input" runs all important windows at the beginning of the input of new task. The input is faster.
