## Function

- Produce a detail deformed shape, SFD/BMD, maximum stress distribution and sectional stress distribution diagrams for a particular section. Transformed section for tendons is not considered in Beam Detail Analysis. If a load combination, which contains moving loads, Beam Detail Analysis cannot be checked.
- Stresses can be calculated at any points of the section for the various section types (DB, PSC, Tapered Section, Composite Section, General and Composite General Section).
- The details are as follows.

Section type | Stress Point | Tendon | Reinforcement | |
---|---|---|---|---|

General Section in DB/User and Value | OK | OK | No | |

Value | No | - | - | |

SRC | No | - | - | |

Combined | No | - | - | |

PSC and PSC Value | OK | OK | OK | |

Tapered | DB/user and General Section | OK | OK | No |

PSC and PSC Value | OK | OK | OK | |

**Applied Forces/Moments [Fx, Fy, Fz, Mx, My, Mz]** : Member forces at the position along the length assigned by the user

The results produced in the Diagram and the Table can be different from those of Beam Detail Analysis since the moment of inertia can be different depending on the way of applying the axis (local direction). (Refer to ** 1** In Beam Detail Analysis, the section properties at the positions (1/4, 1/2 & 3/4) are re-calculated using the section shape information at the corresponding positions whereas in diagrams and tables, section properties at the positions (1/4, 1/2 & 3/4) are obtained by interpolation between i-end and j-end.)
