I'm new on this forum. I'm a structural engineer from Poland and I use AISC-341-10 to design a structure for high seismic region.
Due to the reason of huge seismic base shear force I need to design my structure as a Special Concentrically Braced (SCBF).
"Braces shall be determined to be in compression or tension neglecting the effects of gravity loads."
I kindly ask for help me to unerstand. The braces are not designed for any gravity loads? Only for horizontal load from seismic?
Is it means that my braces can be overloaded during the state of gravity loads (without any seismic or wind) and I'm sure if I use slederness requirements they will.
Thank you for answers in advance!
