section properties

Hi all,

my query is regarding section properties.

 If i want to add a new section using modify section propeties,What all the parameters required? I am little confused how the coordinates are considered.what does ct,Zx,Zy values represent?If  Z is the major axis,There is no Zz value but Zx is given.

kind regard,

Babu

  • Hi 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,

    Chris
