I am analyzing joists for some new snow drift loading and some of the web members are crimped angles. In the SJI Table 4.3-1 in Section IV for Web Members it says to use a k of 0.75 for kl/rx and a k of 0.9 for kl/ry. Since the equal leg angle is rotated 45 degrees for a crimpled condition which is the rx direction and which is the ry? Is it correct to use a k of 0.75 or 0.9 for this condition?
For what it is worth I am modeling the joist in RISA and do have these web members physically rotated in the correct orientation.
Thanks!
