Usfos Joint Examples.

For many strucutres, the tubular joint connections (the welded connection between the brace and the chord) are weaker than the basic members. Assuming node-node connected elements is non-conservative for such structures. In order to describe the tubular joint behaviour correctly, the following modeling is needed:

Figure 1 describes how Usfos automatically modifies the conventional Node-Node model to a model with two extra nodes and elements.

Usfos has different models for the tubular joint behaviour:
