Hello Dear Engineers,
ETABS' Steel Frame Design Manual says,

Again,

What I understand is ETABS produces auto-generated load combinations based on the user-defined load patterns and load cases depending on specific user-chosen design code and seismic preferences. I believe ETABS can work on the auto-generated seismic load combinations and apply on them the overstrength factor internally to perform the "special check for column".

What if the load combinations are user-made rather than being program-generated? Is ETABS going to apply the overstrength factor internally to perform the "special check for column"?
