In a singly reinforced beam Elastic moduli for concrete and steel have different values within the limits of deformation of the beam Compression is borne entirely by concrete Plane sections transverse to the centre line of the beam before bending remain plane after bending Steel possesses initial stresses when embedded in concrete 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 35 40 45 30 TRUE ANSWER : ? YOUR ANSWER : ?
The minimum thickness of a flat slab is taken L/36 for end panels without drops All listed here L/32 for end panels without drops L/36 for interior panels without drop TRUE ANSWER : ? YOUR ANSWER : ?
In a beam the local bond stress Sb, is equal to Shear force/(Leaver arm × Total perimeter of reinforcement) Leaver arm/(Shear force × Total perimeter of reinforcement) Total perimeter of reinforcement/(Leaver arm × Shear force) Leaver arm/(Bending moment × Total perimeter of reinforcement) TRUE ANSWER : ? YOUR ANSWER : ?
A pre-stressed concrete member is preferred because Large size of long beams carrying large shear force need not be adopted Removal of cracks in the members due to shrinkage Its dimensions are not decided from the diagonal tensile stress All listed here TRUE ANSWER : ? YOUR ANSWER : ?
In the zone of R.C.C. beam where shear stress is less than 5 kg/cm², nominal reinforcement is provided at a pitch of Lever arm of the section One and half lever arm of the section One-third lever arm of the section One-half lever arm of the section TRUE ANSWER : ? YOUR ANSWER : ?
The load stress of a section can be reduced by Increasing the total perimeter of bars Replacing larger bars by greater number of small bars Decreasing the lever arm Replacing smaller bars by greater number of greater bars TRUE ANSWER : ? YOUR ANSWER : ?
An intermediate T-beam reinforced with two layers of tensile steel with clear cover 13 cm encased with the floor of a hall 12 meters by 7 meters, is spaced at 3 meters from adjoining beams and if the width of the beam is 20 cm, the breadth of the flange is 236 cm 233 cm 300 cm 176 cm TRUE ANSWER : ? YOUR ANSWER : ?
The maximum shear stress (q) in concrete of a reinforced cement concrete beam is (Shear force × Width)/Lever arm Width/(Lever arm × Shear force) Lever arm/(Shear force × Width) Shear force/(Lever arm × Width) TRUE ANSWER : ? YOUR ANSWER : ?
