View/Update

The View/Update command works similarly for C-Beamâ„¢ design as for Steel beam design. The design of individual members can be viewed, altered, and saved.

When a beam with no assigned size is selected, the optimized size is shown highlighted in the Beam Size list. Fy and, for composite beams, the required number of studs are also shown. For Castellated beams the optimum value for dt is shown, and the range of acceptable e values, emax and emin, are listed. In addition, the range of phi values for the Top and Bottom tees are also shown. Phi ranging from 58 to 62 degrees is always investigated. For asymmetric Castellated beams, the range for the Top and Bottom tees differ but fall in the range from 58 to 62 degrees. Since e and phi affect the spacing of the holes, the range of acceptable e and phi values allow the manufacturer to space the openings as necessary to facilitate the connections at the ends of the beam. For Cellular beams, Do and the acceptable range of S are listed.

When a beam with an assigned size is selected, the assigned size is shown highlighted in the Beam Size list. The values assigned for dt, e and phi or Do and S are also shown. The Optimize check boxes for dt, e and phi or Do and S are also checked. To investigate alternate dt, e and phi or Do and S, uncheck the respective Optimize check box and edit the the corresponding edit fields. The Optimize and Analyze commands respect the state of the Optimize checkboxes when invoked. An unchecked Optimize checkbox against dt, e or phi or Do or S makes the parameter user-assigned. For Castellated beams, the user may assign a Top or Bottom tee phi by first unchecking the phi Optimize checkbox and selecting either the Top or Bottom phi radio button.

Note: The Analyze command investigates the current beam size selection while enforcing the state of the Optimize checkboxes while the Optimize command enforces the state of the Optimize checkboxes but disregards the current beam size selection.

When a new size is selected from the Beam Size list and an Analyze performed, values of dt or Do and ranges for e or S and phi are inserted into the dt, e and phi (or Do and S) edit boxes, respectively. Those values are either the optimized values or user-specified values, depending on the state of the corresponding check boxes.

The critical configuration or configuration of dt, e and phi (or Do and S) with the worst interaction value (controlling interaction) is displayed at the bottom of the View/Update dialog box. Alternate beam configurations corresponding to the minimum, maximum or controlling e (or S) and phi may be viewed by selecting any of the listed e (or S) or phi values from the combo boxes immediately above the graphic. The interaction values for all design checks performed are also shown.

The Openings Data lists the locations of posts and openings and the controlling post or opening is highlighted in blue. Similarly, the controlling post or opening in the beam configuration window at the bottom of the View/Update dialog box is also highlighted. When an analyzed user-specified configuration fails, the failing post or cell is highlighted in red.

The locations of supported beams are indicated by a pair of triangles in the graphic. The position of transfer columns are also indicated by a single triangle above the graphic.

The ability to infill openings can only be performed on beams with a specific dt, e and phi in the case of Castellated beams and Do and S in the case of Cellular beams.

Note: e (or S) is specific if the minimum and maximum values assigned to the range are the same.

To infill an opening, double-click the opening in the graphic at the bottom of the View/Update dialog box or double-click an opening location in the Openings Data list. To remove infills, double-click the infill in the graphic or opening location in the Openings Data list.

Design results can be viewed by selecting View Results. A more detailed report can be viewed by selecting the View Detailed Results button.

Size, opening, and stud configuration can be saved back to the database by selecting Update Database.
