A singly-reinforced rectangular concrete beam of width 300 mm and effective depth 400 mm is to be designed using M25 grade concrete and Fe500 grade reinforcing steel. For the beam to be under-reinforced, the maximum number of 16 mm diameter reinforcing bars that can be provided is

In shear design of an RC beam, other than the allowable shear strength of concrete $ \style{font-family:'Times New Roman'}{\left(\tau_c\right)} $ , there is also an additional check suggested in IS 456-2000 with respect to the maximum permissible shear stress $ \style{font-family:'Times New Roman'}{\left(\tau_{c\;\max}\right)} $ . The check for  $ \style{font-family:'Times New Roman'}{\tau_{c\;\max}} $ is required to take care of

Consider the singly reinforced beam section given below(left figure). The stress block parameters for the cross- section from IS: 456-2000 are also given below (right figure). The moment of resistance for the given section by the limit state method is ______ kN-m.


A simply supported reinforced concrete beam of length 10 m sags while undergoing shrinkage. Assuming a uniform curvature of 0.004 m-1 along the span, the maximum deflection (in m) of the beam at mid-span is _________.
