Question

3. The ratio of the limiting value 1 poi
of the depth of neutral axis and
the depth of the section of a
singly reinforced beam is equal
to:​

Answer 1

Answer:

Therefore, the depth of the neutral axis has a limiting or maximum value = x u, max. Accordingly, if the Ast provided yields x u > x u, max, the section has to be redesigned. Since x u de p ends on the area of steel, we can calculate Ast, lim from Eq. 3.17.
