From my understanding, sustained loading is essentially dead load as it is a long term load applied to the structure.
When carrying out a design using profis using characteristic forces, would I therefore leave the permanent loading blank and only fill in the variable load and sustained load?
Hi, thanks for your question.
Your understanding is partly correct. A sustained load is the portion of the load acting over a long period, but it does not replace the permanent load in PROFIS Engineering.
When using characteristic loads, enter the permanent and variable actions in their respective fields, and use the sustained-load field to define the portion acting long term for creep consideration in bonded anchors. Therefore, the permanent-load field should not be left blank where a permanent action exists.
