In RFEM, I want to load a circular ring displayed as a member with the load generator. However, the curved member is not taken into account. What is the reason?


The function [Generate Loads → From Area Load on Members via Plane...] requires the defined plane to be created from a continuous line. If a curved member is created from arcs, the plane as a polygon cannot find the outer contour of the arc, because it is only an approximation. In short, curved members cannot be loaded by means of the load generator in RFEM.

In this case, it is recommended to display the curved member by means of several straight member segments. Thus, the continuous line can be run cleanly. In order to create the corner nodes of the polygon chain more quickly, it is advisable to prepare them e.g. in Excel, depending on the number of member segments. The numbering of nodes is important. The procedure is demonstrated in the video.
