Question
There is a note in the RF-/JOINTS Timber - Steel to Timber add-on module saying that the member length is too short. What is the minimum length and how to avoid the problem?Answer
To define a dowel connection, the add-on module requires the minimum member length. This is 42 cm. If a member is shorter, the text "Member is too short" appears in Window "1.2 Nodes and Members" (see Figure 01). However, the structural component is often broken by intermediate nodes, and consists of several members. In such cases, the structural component can remain as a member in RFEM and the nodes can be used with the "Create Node 'On Line'" feature (see Figure 02). Thus, the member is not divided. All members connected to these nodes are then connected to each other, even if the member is not divided. As an alternative, it is possible to use the "Divide Member" feature with the "Place new nodes on the line without dividing it" option (see Figure 03).Keywords

Often, models are needed in several projects, like the purlin with columns and knee braces in this example. The dimensions can be changed directly in RFEM or RSTAB by shifting the nodes.
