Process - Results Deflections
The Deflection Results dialog box provides interactive access to the deflection results.
By selecting a deflection type from the drop-down list the members are colored according to their deflection ratio (Calculated Ln/d divided by Allowable Ln/d) for the selected load type. If however there is no design (no reinforcing) in a beam, the beam will be colored white. If there is no deflection criteria specified (or a beam has a span/depth ratio less than specified to be checked) in the Criteria-Deflection dialog box then all the beams will be colored light blue. All other case the beams are colored according to the deflection ratio color scale and the selected deflection type. If desired the Controlling Case can be selected from the deflection results dialog to display that deflection type on each beam that produced the worst deflection ratio.
By selecting one of the text display options and clicking Apply, the selected entity will be displayed for each beam on the screen. The available selections are as follows:
| Setting | Description |
|---|---|
| Ln/d | The clear span (face-to-face) span length-to-depth ratio (for cantilevers twice the clear span is used for L). 'd' is the full depth of the section. If Controlling Case is selected in the Deflection Type list box then the controlling deflection type is shown on the member (DL=Dead Load, LL=Live Load, LT = Long Term + Live and NET = DL + LT + LL - Camber). |
| Delta | The deflection for that physical member that corresponds to the largest L/d for all spans in the physical beam. That is, for a beam that has a cantilever only one delta is reported per deflection type per beam. This delta is the deflection that corresponds to the largest L/d for each span (mid span and cantilever) on that individual beam. |
| Ieff | The calculated effective moment of inertia for the beam for that particular deflection type. |
| DefL Ratio | If there is an allowable deflection limit specified (in the Criteria-Deflection Dialog Box) for the selected Deflection Type, the controlling deflection ratio (Actual deflection / Allowable Deflection) will be reported. Note that each member is colored according to its deflection ratio for the selected deflection type. |
