The maximum permissible size of aggregates to be used in casting the ribs of a slab, is 7.5 mm 10 mm 15 mm 5 mm TRUE ANSWER : ? YOUR ANSWER : ?
According to load factor method, the permissible load ‘W’ on a short column reinforced with longitudinal bars and lateral stirrups, is Stress in concrete × area of concrete + Stress in steel × area of steel None of these Stress in concrete × area of concrete Stress in steel × area of steel TRUE ANSWER : ? YOUR ANSWER : ?
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 45 35 30 40 TRUE ANSWER : ? YOUR ANSWER : ?
An R.C.C. beam of 6 m span is 30 cm wide and has a lever arm of 55 cm. If it carries a U.D.L. of 12 t per m and allowable shear stress is 5 kg/cm², the beam Is safe with stirrups Is safe with stirrups and inclined bars Needs revision of section Is safe in shear TRUE ANSWER : ? YOUR ANSWER : ?
If diameter of a reinforcement bar is d, the anchorage value of the hook is 12d 4d 8d 16d TRUE ANSWER : ? YOUR ANSWER : ?
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)⁴ w₁/w₂ = (l₂/l₁)³ w₁/w₂ = (l₂/l₁)² TRUE ANSWER : ?
