Thermal load on beam

The load is defined by means of a single value. The value specifies the warming to which the 1D member is subject.

The load is defined by means of a set of four values. The individual values specify the temperature at individual sides (top, left, bottom, right) of the 1D member.

If ON, the load is defined by means of specified thermal distribution curve.

This parameter specifies the direction from which the heat "comes", i.e. which face of the beam is exposed to the fire.

Specifies the temperature distribution curve that is used to determine the final load.

The actual distribution of the heat over the cross-section is generally non-linear (defined by the temperature distribution curve). The calculation algorithm, however, required a linear distribution. Therefore, the program must transform the curve into a trapezoid. The accuracy of this approximation can be controlled by this parameter. The higher the input number, the better accuracy and the more demanding (longer) the calculation.

The parameter can be from the interval <5, 50>.
