Is it possible to model a semi-rigid composite beam with a line release using members in RFEM?


Yes, it is possible. For this, you should ensure that one beam is only modelled first, whose lines are released with a line release. You will then add another member to the automatically generated copies of the lines.

For split beams, make sure that both members connected on the nodes are released in the table of line releases. Under Downloads below, you can find an example of a composite plate made of timber and concrete from [1] as a calculated model and the workflow as a video.
