Section 18.8.2 Minimum Bonded Reinforcement
The minimum bonded reinforcement is provided in accordance with the following table.
Member Type | Tensile Stress, | Tensile Stress, | ||
---|---|---|---|---|
Type of Tendon | Type of Tendon | |||
Bonded | Unbonded | Bonded | Unbonded | |
Beam | 0 | 0.004A | 0.003A | 0.005A |
One-way Slab | 0 | 0.003A | 0.002A | 0.004A |
Two-way negative moment regions | 0 | 0.006hln | 0.0045hln | 0.0075hln |
Two-way positive moment regions | 0 | 0.004A | 0.003A | 0.005A |
Two-way positive moment regions | 0 | 0 | n/a | n/a |
For sections with multiple concrete strengths, the minimum concrete strength is used to determine the limiting stress.
For sections with multiple concrete strengths, approximate extreme fiber stresses and centroid stresses are reported.
