Hello,
While analyzing and designing a continuous structure, there is an option for negative moment continuity steel. As outlined in the Tutorial PDF T1A-5 (pg. 47), we input the continuity steel but when looking at the strand patter design status, there is no change to the service III stresses at the precast top at bearing, transfer zone, and at h/2. Is that steel being considered at all? is it only for rating purposes? additionally, it does not show in the elevation diagram of the beam.
See pictures.

Thanks.
I beam is designed as uncracked section and the deck as cracked section.
Generally the rebar for negative moment continuity steel is provided in the Rebar Pattern Dialog box.
Results can be seen in the Reinforced Design report.
The Rebar provided inside the girder at the top does not help in the reduction of stresses.
Please see the detail explanation in the Bentley communities link provided below.

Please let me know if you need any additional information.
Thanks Vinay
