The Deflections tab provides the engineer a means to view the results of the controlling deflection check on each beam in the beam line.

For each span in the beam line the engineer can view the camber (if specified to be calculated in the Criteria-Camber dialog box), the type of deflection that controlled (Dead Load, Live Load, Long Term or Net), what the controlling deflection (delta) value is, where along the span this controlling deflection was calculated, the controlling span-to-deflection ratio, the effective moment of inertia for the controlling case, the controlling ratio (calculated L/d divided by Allowable L/d). Note that a controlling deflection is only available if the user has specified at least one set of criteria in the Criteria-Deflection dialog box, otherwise the largest deflection and associated data is reported.

The user can update the reinforcing on the Longitudinal reinforcing tab, select Analyze and return to the Deflection tab to observe the affect on the deflection checks. Note that a change of tension steel will affect immediate deflection values (Dead Load and Live Load) predominantly, whereas modifying the compression reinforcing will also affect the long-term deflection results.
