Structure Pipeways

Structure pipeways may be defined on any floor of a structure. These pipeways are built in the Pipeway Builder.

Building a Structure pipeway

  1. Open the Pipeway Builder.
  2. Select Structure Pipeway in the Pipeway Type area of the dialog.
  3. Enter the desired Structure, Section, and Floor for the pipeway.
  4. Choose a Centerline Location option (structure pipeway origins are at the center of the bottom of the first bent – like external pipeways):

    By Bay allows you to place the pipeway origin by specifying the East-West and North-South bay of the structure.

    Note: This is the recommended technique for locating a structure pipeway.

    or

    By Section Coordinates allows you to enter local coordinates for the pipeway origin.

    or

    By Global Coordinates allows you to enter global coordinates for the pipeway origin.

  5. Enter the Pipeway Origin data based on the Centerline Location option:

    For By Bay (see above image) enter the Orientation of the pipeway, the East-West Bay Number where the origin is to be placed, the North-South Bay Number where the origin is to be placed, and the Alignment of the pipeway (left, right, or center of bay).

    or

    For By Section Coordinates enter the X and Y coordinates for the origin of the pipeway with respect to the origin of the structure section and the Orientation of the pipeway. (The Z-coordinate is set by default from the floor the pipeway is on.)

    or

    For By Global Coordinates enter the X and Y coordinates for the origin of the pipeway as well as the Orientation. (The Z-coordinate is set by default from the floor the pipeway is on.)

  6. Enter the Section Number.
  7. Enter the Structural Member information:
    1. Bent Type is either Floor-to-Ceiling or Trapeze
    2. Column Shape, Beam Shape, and Lateral Shape are all selected from the steel table (as shown in Appendix A - Default Data Tables).
      Note: For no laterals, select <none> in the lateral shape drop down list.
    3. The Drop Zone is either inside or outside.
    4. The Edge Space is the amount of space to be reserved on both sides of the pipeway.
    5. The Hot Side will be empty until the pipeway has been accepted, after that the program will select <default> with the directions perpendicular to the pipeway’s orientation available in the drop down list.
  8. Fill in the Size information for the pipeway.
    Note: Generally this information will automatically update with the selection of the structure section and pipeway orientation.
    1. Width is the distance between column center lines in a bent.
    2. Number of Bents is the number of bents in the current section (like external pipeways, all sections have a beginning and ending bent).
    3. Number of Levels is the number of pipe-supporting beams in a bent.
    4. Lowest Level Elevation is the elevation of the lowest level of the pipeway, from this value the other levels are placed.
      • The Lowest Level Elevation can be selected from the (preferred levels) drop down list; this list contains the available values for the pipeway’s lowest level based on project set-up data.

      As with Main and Secondary pipeways, you can define variable spacings between levels by selecting the Variable Elevations checkbox and entering the elevations for all the approach and berthing levels.
