Reactions

The reactions loading each side of the column are calculated. If a beam is skewed with respect to the column, its reaction is split into orthogonal components and added to the values from the appropriate sides of the column. The split is based on the ratio of the angle.

For example, a skewed beam with a 10 kip reaction frames into the column between sides 1 and 2 at an angle of 20° from side 1. The 10 kip reaction is split as follows:

R1: $\frac{90 ° - 20 °}{90 °} \times 10 kips = 7.78 kips$

R2: $\frac{20 °}{90 °} \times 10 kips = 2.22 kips$

Depending on the connection configuration and the angle at which the beam frames into the column, it may be appropriate to suppress the splitting of the reaction and apply the full reaction to a single side of the column. The user may specify the maximum angle at which reactions will not be split. If the angle between a given column axis and the beam is greater than the angle specified the reaction will be split between the two adjacent sides; if the angle is less than the angle specified the full reaction will be applied to the closest side.
