Hey all,
I am wondering if anyone has ever come across a reference that shows what the yield strength of the web members typically used in these "Hat Shape" joists as seen in the screenshot below:
The interior web members are typically hollow tubes, so I have been using the DN A53 pipes and going to the nearest size rounding down, and taking 240MPa for my yield. However, every other type of old OWSJ, whether it be Omega or Anthes joists, have been anywhere from 300MPa to 380MPa. I haven't had any success finding a manufacturers table or reference on these joists.
