The base material at the location of a weld may have less strength than the weld itself. In this case it will control the overall strength of the welded connection. In order to account for this, RISAConnection uses a weld strength reduction factor (α) which we call the Base Material Proration Factor. This factor is […]

RISAConnection assumes by default that your vertical brace connection is a one-sided connection without any outside influence or load transfer from other connected elements.  Using this assumption, the design shear and axial force at the beam to column sub-connection is determined using simple statics per the Uniform Force Method in the AISC Steel Design Manual.
