In a concentrically braced frame, STAAD.Pro will consider axial hinges for the braces which are declared as truss members. Axial hinges will be considered for the beams and column members too.
In a moment frame, STAAD.Pro considers all members to be frame members except those which are declared as truss member. For beams (i.e., horizontal member) moment hinges will form (deformation controlled). For columns (i.e., vertical member) it can be either force-controlled (axial & bending) or deformation controlled (bending only) depending upon the values of axial forces formed in column as per FEMA 356 2000 guidelines.
