Double Angle dialog

Used to specify the section properties for a double angle user defined table section.

Opens when you click Add in the User Table Manager dialog when a Double Angle section table is selected.

SettingDescription
Section Name Type a section name used to identify the shape in the table.
D Depth of angle (i.e., length of the leg along the local y-axis)
WF Width of angle (i.e., length of the leg along the local z-axis)
TF Thickness of angle leg
SP Space between angles.
Cross Section Area (Ax) Cross section area. Can be automatically calculated by clicking the Calculate button.
Inertia About Local z (Iz) Moment of inertia about local z-axis (usually strong axis). Can be automatically calculated by clicking the Calculate button.
Inertia About Local y (Iy) Moment of inertia about local y-axis. Can be automatically calculated by clicking the Calculate button.
Torsional Constant (Ix) Moment of inertia about local x-axis. Can be automatically calculated by clicking the Calculate button.
C.G. along local Y (Cy) Distance from the face of angles to the center of gravity (C.G.) along the local y-axis. Can be automatically calculated by clicking the Calculate button.
Shear Area in Y (Ay) Shear area in local y-axis. If zero, shear deformation is ignored in the analysis. Can be automatically calculated by clicking the Calculate button.
Shear Area in Z (Az) Same as above except in local z-axis. Can be automatically calculated by clicking the Calculate button.
Single Angle (rvv) The radius of gyration about the minor principal axis for single angles - z-z axis for TA ST angles, and y-y axis for TA RA angles.
SettingDescription
OK Saves the UPT section and closes the dialog.
Cancel Closes the dialog without creating a new section.
Calculate Click to calculate the Iz, Iy, Ix, Cy, Ay, and Az values from the provided section dimensions.
