How to change analysis type

You can easily change the analysis type in the upper ribbon.

The abbreviations stand for:

EPS – Stress/strain design (joint code-check, optional buckling analysis)

ST – Connection stiffness (rotational/axial stiffness of selected member connection)

MC – Member capacity design (code-check of non-dissipative connections for seismic design)

DR – Joint design resistance (maximum possible loading, reserve in joint capacity)

There is also another option. Choose the tab Project and follow the figures below.
