Factor Cm
This functionality is in
beta stage
.
Factor Cm
public
Factor used to calculate moment application factor as per AS4100:2020 Section 4.4.2.2
IF
$ 0.6 - 0.4 * \beta_{m_{AS4100}} $ > $ 1 $
THEN
$$ c_{m_{AS4100}} = {1} $$
OTHERWISE
$$ c_{m_{AS4100}} = {0.6 - 0.4 \cdot \beta_{m_{AS4100}}} $$

Bending moment ratio
public
The ratio of the smaller to the larger bending moment at the ends of the member, taken as positive when the member is bent in reverse curvature as per AS4100:2020 Section 4.4.2.2
$$ \beta_{m_{AS4100}} = -1 \: $$
