3.1.4 Fire Resistance

Fire Resistance

This tab manages detailed settings for the fire resistance design.

Figure 3.5 Dialog box Details, tab Fire Resistance

In addition to the Required time of fire resistance and the Time interval needed for the determination of the temperature change, you have to define the Temperature Curve to determine the gas temperature. Three curves are available for selection (see Figure 3.6 to Figure 3.8).

The Factors for determination of net heat flux according to [9] and [2] are preset. However, you can adapt them to specific conditions.

Figure 3.6 Standard temperature-time curve
Figure 3.7 External fire curve
Figure 3.8 Hydrocarbon curve

When you select the check box for Define final temperature manually, you can enter the temperature Θa in Windows 1.10 and 1.11 individually.
