Hi, i've had a similar problem to this before, however, i'm not sure what is going wrong now.
I have a 2d Portal frame, when I check the member utilization with the haunch, the utilisation is much greater than without it.
This is for the same location along the member as well.
Robot is calculating the LTB parameters differently and providing a much smaller Xlt value with the haunch.
Please see the screenshots.
