Structural Fire Analysis

Extension Module for the 3D FEM Calculation

Analysis of 2D and 3D beam and shell structures with steel, reinforced concrete, timber and composite sections in accordance with EN 1992-1-2, EN 1993-1-2, ENV 1994-1-2 and EN 1995-1-2.

  • Any kind of section geometry
  • Steel, reinforced concrete, timber and free materials (e.g., insulation) within a section
  • Predefined and user-defined thermal material properties
  • Standard temperature-time curve, hydrocarbon fire curve
  • User-defined fire curves
  • Calculation of the temperature profile in the section via nonlinear time-step integration
  • Consideration of different fire scenarios
  • Temperature-dependent thermal strains and stress-strain curves
  • Nonlinear time-step calculation of the structure based on the general calculation method

Thermal analysis for solid structures.

  • Stationary and instationary thermal analysis
  • Time-dependent heat source
  • Stress analysis with the calculated temperature distributions

Graphical display of the time-dependent temperature distributions, deformations, internal forces and support reactions.
