I am sorry but I didn't quite clearly understand what 271828 said..Is there any explanation for my doubt based on mechanics of rectangular section?
Is it because d<<<b that when the section bends about the minor axis there is not much difference between its nominal moment capacity and plastic...
Hi,
How is that for a rectangular cross-section bent about the minor axis, the nominal moment strength is equal to plastic moment capacity??
Isn't nominal moment strength = stress x b x d^2/6
plastic moment capacity = stress x b x d^2/4
