Info

For a corner panel use structural system 2.

It may be normally assumed that slabs are lightly stressed (p < 0.5%).

NAD 6.4(e) and (f) allows the basic span/effective depth ratio to be interpolated, according to the reinforcement provided, for values in the range 0.15% < p < 0.5%.

For the span moment A = 441 mm2/m r s,req s,prov

NAD Table 7

Basic span/effective depth ratio (p = 0.27%) = 39.9

Using reinforcement with f > 400 N/mm2, this value should be multiplied 4.4.3.2(4)

to reflect the actual service steel stress by the factor
