# 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.

Setting | Description |
---|---|

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. |
