This is a template attribute. Template attributes can be used in filtering, or to retrieve data from the model to use in drawings and reports. For example, when you create a report, Tekla Structures replaces the attributes added in the report template with the corresponding object property values.

This custom template attribute shows the weight of a concrete element. The element weight is calculated as follows:

The volume of concrete parts minus the volume of steel embeds, reinforcing bars, and reinforcement meshes is multiplied by a concrete density of 2450 kg/m3 (hard-coded) to achieve the concrete weight. Then the weights of the concrete, reinforcement, embeds, and surface treatments are summed up.

The calculation uses a steel density of 7850 kg/m3 for steel embeds and reinforcement. Steel embeds and reinforcement are assumed to be completely within the concrete.

For cast units with dense reinforcement, this template attribute is more accurate than CUSTOM.ELEMENT_WEIGHT.

You can also use the CUSTOM.ELEMENT_WEIGHT.DETERMINING attribute. It shows the value of CUSTOM.ELEMENT_WEIGHT or CUSTOM.ELEMENT_WEIGHT.REINFORCED, whichever has the higher value.
