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.
