Question 1
Usually stiffness of a simply supported beam is satisfied if the ratio of its span to depth does not exceed which one of the following?
Question 2
When is an RCC roof slab designed as a two way slab?
Question 3
In a singly reinforced beam, the tensile steel reaches its maximum allowable stress earlier than concrete. What is such a section known as?
Question 4
What shall be the maximum area of reinforcement (i) in compression and (ii) in tension to be provided in an RC beam, respectively, as per
IS : 456?
IS : 456?
Question 5
In limit state design method, the moment of resistance for a balanced section using M20 grade concrete and HYSD steel of grade Fe415 is given by 
What is the value of K?
What is the value of K? Question 6
The RC slab, simply supported on all edges as in figure below, is subjected to a total UDL of 12 kN/m2. The maximum shear force/unit length along the edge ‘BC’ is
Question 7
As per codal provisions in two way slabs, the minimum mild steel reinforcement to be provided in the edge strip is
Question 8
Assertion (A): In limit state design, over-reinforced sections are not permitted.
Reason (R): As the concrete failure is brittle, the structure fails suddenly without any warning.
Reason (R): As the concrete failure is brittle, the structure fails suddenly without any warning.
Question 9
Assertion (A): Minimum shear reinforcement in all shallow beams is provided when shear stress exceeds 0.5
(where 
is design shear stress).
Reason (R): Minimum shear reinforcement prevents formation of inclined cracks and avoids abrupt failures and introduces ductility in shear.
(where is design shear stress). Reason (R): Minimum shear reinforcement prevents formation of inclined cracks and avoids abrupt failures and introduces ductility in shear.
Question 10
Assertion (A): The concept of locating the neutral axis in a reinforced concrete flexural member as centroidal axis is applicable in working stress design method, but not in limit state design method.
Reason (R): The working stress design method assumes that the structural material behaves in a nonlinear elastic manner and there is strain compatibility in bond between steel and concrete.
