    a. Bend & Miter Piping Components - Modeling Approaches, Tips, Techniques used in AutoPIPE

    Attention: Please see the following AutoPIPE help section:
    Help > Contents> Contents Tab> Modeling Approaches> Modeling Approaches>

    This help has been provided in order to give users ideas for modeling typical piping arrangements. The steps shown in each example should not be taken as the only method available to create models. In addition, the intent of the examples is to present ways to create adequate models of specific piping components for analytically purposes.

              Anchors        Bends
              Cuts              Flexible Joints
              Frames         Hangers
              Nozzles        Pipes
              Reducers      Rotating Equipment
              Supports       Tees
              Valves           Vessels

    Note: AutoPIPE does calculate the element stiffness matrix of a bend differently from a straight pipe. The stiffness matrix was originally taken from SAP IV  ( click here for technical manual ) which acted as the basis for AutoPIPE analysis engine. This is not the original SAP IV manual, and note that it acted only as a basis.
