Hi Sean.
In the lecture video at 8:30 you include a Compression Limit of 0.38. What does this represent, please? I can’t remember covering this in any of the preceding lectures …
Hi @alexboye - We cover this in lecture 19, at about 18:49. It’s basically a check to ensure that the compression steel has yielded at ULS (as per our assumption).
