Assalam o alaikum,
Can any one tell me what is maximum limit of positive and negative steel ratios in slabs and footings? ACI code is giving me minimum limit in terms of percentage of gross area i.e. 0.002.b.h or 0.0018.b.h. but it reports maximum allowed reinforcement in terms of net tensile strain in tension reinforcement. Kindly explain what value it means in terms of gross area for maximum allowed steel ratio to avoid over-stressing of slabs and footings?
