Multi-Cell CIP Box Parts Dialog Box

The Multi-Cell CIP Box Parts dialog box allows you to create, modify, and delete additional cross section parts. To open this dialog box, click the Cross Section button on the Geometry tab to open the Cross Section Layout dialog box. Select the section you want to modify, click the Section button to open the Multi-Cell CIP Box Section dialog box, then click the Parts button located at the bottom of the screen. Any number of parts can be added and parts can be added or removed at any time. The order of the parts is inconsequential. Note that the parts are made of the same material as the main section.

Adding New Parts

Perform the following steps to add a part:

Click the Add Part button. This adds a part after the active definition.
Enter the part values in the grid. A definition for each parameter is available below.

Deleting Parts

Perform the following steps to delete a part:

In the grid, select the part you want to delete by clicking anywhere in its row. A blue arrow displays on the left side of the grid to mark the selection.
Click the Delete Part button to remove the selected part.

Grid Definitions

Setting

Description

Type

Using the drop-down list, select the standard type of geometric part to be located by its reference point.

Setting	Description
Rectangle	A rectangle located by referring to one of its corners.
Triangle	A right triangle (90°).
V-Parabolic	A parabola with its zero slope relative to its vertical axis.
H-Parabolic	A parabola with its zero slope relative to its horizontal axis.
Sector	A quarter of an ellipse.
Circle	A circle or an ellipse located by its center.
Cove	A shape made of a rectangle by taking a quarter ellipse out of it.
Blob	A general shape defined by its arc and moment of inertia.

Sub-Type

Using the drop-down list, indicate the reference location of the part shape, according to the graphic view. The reference point for the full section is top center of the section.

Setting	Description
Bottom/Left	Part reference at the bottom left corner.
Bottom/Right	Part reference at the bottom right corner.
Top/Right	Part reference at the top right corner.
Top/Left	Part reference at the top left corner.

Status

Using the drop-down list, indicate whether the part properties should be added (solid) or subtracted (hole) from the section's total properties.

Ref-Z

Enter the z-axis reference location for the part. This is the distance from the section reference (center of the top slab) or girder reference (middle of top of the girder web) to the reference point of the part.

Ref-Y

Enter the y-axis reference location for the part. This is the vertical distance from the section or girder reference to the reference point of the part.

Enter the width of the part.

Enter the height of the part.

Area

The area of the blob part.

Izz

The moment of inertia of the blob part.

Technical Discussion

Parts are defined at section location and the cumulative properties of all parts remain constant over the distance to the next cross section. Part dimensions are not interpolated.
