How does ideCAD calculate internal forces for Special Concentrically Braced Frames according to AISC 341-16?
...
Internal forces to be used in the design of columns, beams, and braces are axial forces, shear forces, and bending moments, that which are evaluated by considering the load combinations, including the earthquake effect loads with the overstrength seismic forces.
In summary, The the members' required strength of beams and their connections are determined with load combinations included , including the overstrength seismic load. factor.
