Analysis of I-H shaped profiles under fire situation

Heating evolution analysis of I-H shaped steel profiles under fire situation (protected and unprotected profiles).
Allows to use typical and user defined fire protections. The user sets the sides which are exposed to fire.
Includes a large number of I-H shaped sections from various countries.

Design Codes

  • EN 1993-1-2:2005
  • CTE DB-SI

Profiles and their properties

It is possible to select profiles from a large database of I-H shaped rolled profiles.
For each profile, it is shown the area, weight per unit length, inertia, radius of gyration, unitary lateral surface and section factor.

Settings of exposed sides to fire

It is possible to select the number of sides exposed to fire from five possible configurations.

Fire protections

It is allowed to use profiles with or without fire protection. The protections can be typified or user defined.
Typified protections are:

  • Mineral fibre spray
  • Vermiculite or perlite plaster spray
  • Low density vermiculite or perlite cement spray
  • High density vermiculite or perlite cement spray
  • Mineral or rockwool
  • Intumescent coating
  • Plasterboard
  • Calcium silicate fibre board
  • Fibre cement board
  • Vermiculite or perlite cement board
  • Rockwool board

Results

A plot with the profile temperature evolution from the beginning of the fire.
The profile temperature, or the minimum protection thickness for a desired profile temperature.
