Per AISC 341-10 section F2.6c(1), the required tensile strength of a SCBF brace connection shall be the expected strength in tension. This method assumes that the connection is part of a frame which has an equal and opposite connection across from it. Because of the multiple possible load cases in seismic braces, it is not clear within RISAConnection which Pu/Pa (axial load in the beam) to use to calculate this value.Ġ An analysis in which all braces are assumed to resist forces corresponding to their expected strength in tension or compression. For diagonal brace connections where there is only one brace (either above or below), the program will calculate the controlling brace design force in tension and the controlling brace design force in compression.
