22.2.4.1

For members with bonded prestressing reinforcement conforming to 20.3.1, stress at nominal flexural strength, f_ps, shall be calculated in accordance with 20.3.2.3.

22.2.4.2

For members with unbonded prestressing reinforcement conforming to 20.3.1, f_ps shall be calculated in accordance with 20.3.2.4.

22.2.4.3

If the embedded length of the prestressing strand is less than ℓ_d, the design strand stress shall not exceed the value given in 25.4.8.3, as modified by 25.4.8.1(b).
