Theta angle wich you refer on the interaction surface slide, appears to be the same to the theta angle wich you indicated in the previous slide (related to the cross section subjected to the eccentrical load). I think that's misleading when using the same name for two different angles. Theta angle indicated on the interaction surface refers to the ratio between My and Mx, while the theta angle indicated in the cross section slide is the angle between the resultant eccentricity and the neutral axis. These two directions are perpendicular only in very special cases.
nice teach💜
11:11 it should be zero theta about X axis and 90 degree about y axis.
hello Sir, Do you have any sloved example or material for bulding iteraction surface yourself. (i need it to build in Excel for my thesis)
Thank you.
Very clear presentation.
May I ask you to share the ppt please

Informative video...
bla bla bla, we need how to draw that interaction curve. anyone can refer to charts
