Hi,

I'm studying how ADAPT PT software compute the demand capacity depends on how many percent of PT to be considered in total moment strength with lateral moments change sign.

With the logical equation of Mhyp/Mtotal Cap. = % of Mhyp

But with my experiment consider negative and positive moments near at support, I can't get the correct calculation how Adapt done manually,

Here is the summary results,

Consider x= 0.80m
Secondary Moment = 294.48 knm
Factored Gravity Moment = -2350.176 knm
Factored Lateral Moment = -2426.186 knm

%PT Considered Moment Capacity
0% -2411.8
25% -2699.56
50% -3356
100% -4573.36

I also attached the output in excel.

Please correct me if I'm wrong.

Thanks.
