hi chris,
Sorry for not mentioning the software.I am using staad pro V8i. My query is regarding the section properties in staad.
kind regards,
babu
I see what you are referring to now in the Section Database Manager.
Zx refers to the plastic section modulus about the strong axis. STAAD refers to this as the z axis, AISC refers to it as the x axis.
Zy refers to the plastic section modulus about the weak axis. STAAD and AISC both refer to this as the y axis.
I am not immediately able to correlate the value Ct with a section property in the steel manual, but I will look into it further and get back to you on that one.
Cheers,
Thank you so much for your reply.
For calculating the ct value,do we require to cut the secton at the centre of the I section?
