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

RCC Structures Design
If l₁ and l₂ are the lengths of long and short spans of a two way slab simply supported on four edges and carrying a load w per unit area, the ratio of the loads split into w₁ and w₂ acting on strips parallel to l₂ and l₁ is

w₁/w₂ = l₂/l₁

w₁/w₂ = (l₂/l₁)³

w₁/w₂ = (l₂/l₁)⁴

w₁/w₂ = (l₂/l₁)²

w₁/w₂ = l₂/l₁

w₁/w₂ = (l₂/l₁)³

w₁/w₂ = (l₂/l₁)⁴

w₁/w₂ = (l₂/l₁)²
