A reinforced concrete cantilever beam is 3.6 m long, 25 cm wide and has its lever arm 40 cm. It carries a load of 1200 kg at its free end and vertical stirrups can carry 1800 kg. Assuming concrete to carry one-third of the diagonal tension and ignoring the weight of the beam, the number of shear stirrups required, is

Based on punching shear consideration, the overall depth of a combined footing under a column A, is

(Area of the column A × Safe punching stress)/Load on column A

(Perimeter of column A × Safe punching stress)/(Load on column A × Upward pressure × Area of the column)

None of these

(Perimeter of column A × Safe punching stress)/(Load on column A + Upward pressure × Area of the column)

(Area of the column A × Safe punching stress)/Load on column A

(Perimeter of column A × Safe punching stress)/(Load on column A × Upward pressure × Area of the column)

RCC Structures Design
‘P’ is the pre-stressed force applied to the tendon of a rectangular pre-stressed beam whose area of cross section is ‘A’ and sectional modulus is ‘Z’. The maximum stress ‘f’ in the beam, subjected to a maximum bending moment ‘M’, is

f = (P/A) + (M/6Z)

f = (P/'+ (Z/M)

f = (P/A) + (M/Z)

f = (A/P) + (M/Z)

f = (P/A) + (M/6Z)

f = (P/'+ (Z/M)

f = (P/A) + (M/Z)

f = (A/P) + (M/Z)
