8.19.3.19 IfcStructuralLoadTemperature
8.19.3.19.1 Semantic definition
An instance of the entity IfcStructuralLoadTemperature shall be used to define actions which are caused by a temperature change. As shown in Figure 8.19.3.19.A, the change of temperature is given with a constant value which is applied to the complete section and values for temperature differences between outer fibres of the section.

2 | DeltaTConstant | OPTIONAL IfcThermodynamicTemperatureMeasure |
Temperature change which affects the complete section of the structural member, or the uniform portion of a non-uniform temperature change. |
3 | DeltaTY | OPTIONAL IfcThermodynamicTemperatureMeasure |
Non-uniform temperature change, specified as the difference of the temperature change at the outer fibre of the positive y direction minus the temperature change at the outer fibre of the negative y direction of the analysis member. |
4 | DeltaTZ | OPTIONAL IfcThermodynamicTemperatureMeasure |
Non-uniform temperature change, specified as the difference of the temperature change at the outer fibre of the positive z direction minus the temperature change at the outer fibre of the negative z direction of the analysis member. |
