Satisfy all stress limits for prestressing tendons and concrete as required in Articles 5.9.2.2 and 5.9.2.3. Use limits for severe corrosive conditions in areas of the state where de-icing agents are frequently used or in marine environments.

For all considerations other than preliminary design, determine prestress losses as specified in Article 5.9.3, including consideration of the time-dependent construction method and schedule shown in the contract documents.

Check principal stress in webs as required in Article 5.9.2.3.3.

Check shear and torsion as required in Article 5.12.5.3.8.

Determine tie back reinforcement behind anchorages as required in Article 5.9.5.6.7b. Minimize the amount of tie back reinforcing steel penetrating through segment bulkheads by adjusting the location of anchorages or using hooks for development.

Overhang strength for extreme events, described in Article 9.5.5, is satisfied through TxDOT’s rail crash testing.

Calculate prestress losses for creep, shrinkage, elastic shortening and relaxation as prescribed in Chapter 3, Section 4 - Pretensioned Concrete I-Girders, or by analysis software that has concrete time-dependent capabilities to capture the effect of creep and shrinkage.
