Use the Define Bridge Section Data - Concrete Box Girder - Sloped form to define a deck section parametrically.
Cross-Section. The display area at the top of the form shows a cross section of the template deck section. This is a static display and will not update if any changes are made in the Section Data area of the form. The labels used in this graphic correspond to the parenthetic labeling for the items in the Section Data spreadsheet (e.g., Top Slab Thickness {t1}; Bottom Slab Thickness {t2}; Exterior Girder Thickness {t3} and so forth).
Sketch. The sketch to the right of the cross-cross section will update when changes are made on the form.
Note: If Section is Not Legal appears in red type, review the data in the Section Data spreadsheet area. Click the ? (question mark) to display a message box indicating the problem with the data.
Do Snap check box. When this check box is checked, the mouse pointer will snap to the joints when the mouse is moved over the sketch display. When the check box is unchecked, the mouse pointer can be moved anywhere on the display. The coordinates for the location of the pointer will display in the X and Y display boxes.
Show Section Details button. Click the Show Section Details button to display the Bridge Section Points for {Bridge Section Name} form. When that form displays, the data on that form is not editable, but the display area at the top of that form will update to reflect the changes made in the Section Data area. Note that the Show Section Details button does not appear on the form when the form is accessed from the Bridge Object Data form, as described in Method 2 above.
Modify/Show Girder Force Output Locations button. Click this button to display the Bridge Girder Force Output Location form. Use the form to specify the vertical and horizontal location for reporting force results.
Modify/Show Properties Materials and Frame Sects button. Click the Materials button to access the Define Materials form. Click the Frame Sects button to access the Frame Properties form. Use the forms to define new properties, or review and modify existing properties, as necessary, for the materials and frame sections used for the deck section.
Section Data. This area of the form displays the default geometry for the deck section. Click in a cell in the spreadsheet to type a revised value for that item.
General Data
Bridge Section Name. Use the default section name or supply a revised name.
Material Property. Identifies the material property.
Number of Interior Girders. Specifies the number of interior girders. Click in the cell to type a revised value.
Total Width. Specifies the total width of the deck section. Click in the cell to type a revised value.
Total Depth. Specifies the total depth of the deck section. Click in the cell to type a revised value.
Left Exterior Girder Bottom Offset (L3). Specifies the bottom offset of the left exterior girder. Click in the cell to type a revised value.
Right Exterior Girder Bottom Offset (L4). Specifies the bottom offset of the right exterior girder. Click in the cell to type a revised value.
Slab and Girder Thickness
Top Slab Thickness (t1). Specifies the thickness of the top slab. Click in the cell to type a revised value.
Bottom Slab Thickness (t2). Specifies the thickness of the bottom slab. Click in the cell to type a revised value.
Exterior Girder Thickness (t3). Specifies the thickness of the exterior girder. Click in the cell to type a revised value.
Interior Girder Thickness (t4). Specifies the thickness of the interior girder. Click in the cell to type a revised value.
Fillet Horizontal Dimension Data. Use the f1 through f8 Horizontal Dimension cells to specify the horizontal dimensions of the fillet at the specified location. As noted above, the locations of the various data are shown on the cross-section at the top of the form. Click in the cell to type a revised value.
Fillet Vertical Dimension Data. Use the f1 through f8 Vertical Dimension cells to specify the vertical dimensions of the fillet at the specified location. As noted above, the locations of the various data are shown on the cross-section at the top of the form. Click in the cell to type a revised value.
Left Overhang Data
Left Overhang Length (L1). Specifies the entire length of the overhang on the left side of the deck section. Click in the cell to type a revised value.
Left Overhang Outer Thickness (t5). Specifies the outer thickness of the left overhang. Click in the cell to type a revised value.
Right Overhang Data
Right Overhang Length (L2). Specifies the entire length of the overhang on the right side of the deck section. Click in the cell to type a revised value.
Right Overhang Outer Thickness (t6). Specifies the outer thickness of the right overhang. Click in the cell to type a revised value.
