Question

A member that is obviously supported insufficiently does not lead to the instability of the entire structure. Why?


Answer:
This may be caused by the definition of member eccentricities. For a better overview, the original lines are automatically hidden in the case of eccentric members. In some cases, it may appear that a member end is not sufficiently supported (see Image 01, left). However, the meshed line acts in the background. This can be clearly displayed by hiding the members in the Display navigator (see Image 01, right).

In Image 01, the line at the common node has not been divided geometrically. For this reason, there is no graphical connection line representing the eccentricity in this case. However, because of the setting displayed in Image 02, the node is still meshed with the vertical member.

In order to display the graphical connection line, we recommend dividing the member or the line at this node (see Image 03).
