Perform the fire resistance design with a reduced load-bearing capacity according to the component temperature determined automatically right at the design time. You can determine this automatically according to various temperature curves in the program (a standard temperature-time curve, an external fire curve, a hydrocarbon curve). For other types of temperature determination, it is also possible for you to manually specify the temperature to be applied in the design. You can determine this, for example, according to the parametric temperature-time curve from DIN EN 1991‑1‑2 or from a fire protection report.

With Dlubal Software, you always have an overview, regardless of whether your projects are from the reinforced concrete, steel, timber, aluminum, or other industry. The program clearly displays the design check formulas used in your design (including a reference to the used equation from the standard). These design check formulas can also be included in the printout report.
