ASD - Reinforced Concrete Beam Design Minimum Reinforcement
ASD - Reinforced Concrete Beam Design Minimum Reinforcement
(OP)
I am designing a reinforced concrete beam and the design criteria calls for ASD as the design method. I am used to designing using LRFD, and I am having trouble finding the maximum and minimum reinforcement allowed when designing using ASD. Does anyone know the maximum and minimum reinforcement ratio, or can anyone tell me where I can find this information? Thanks.

That means that the minimum As required by 10.5, and the maximum As required by 10.3.3 apply.
Also note that in subsequent editions of ACI 318 (such as the 02 and 05 versions) the commentary for section 1.1 (R1.1) states that ASD, as included in 318-99, is acceptable, but is not included in the text of these 318 editions.
Minimum and maximum reinforcing is included in the code to prevent sudden failures of flexural members (read the commentaries for 10.3.3 and 10.5)
