Video Solution
Question 64

A rectangular column section of $$250 \times 400$$ mm reinforced with 6 steel bars of $$Fe_{500}$$, each of 25mm diameter. Concrete Mix is $$M_{30}$$. Axial load on column section with minimum eccentricity as per IS 45 6-2000using limit state method can be applied upto:

Video Solution
Question 65

The effective length of circular electrical pole of length L and constant diameter erected on groundis :

Video Solution
Question 66

If $$\psi$$ is the nominal diameterofreinforcing bar, $$f_{x}$$, is compressive stress in the bar and $$f_{bd}$$ is design bondstress of concrete,the anchorage length $$l_{a}$$ of straight bar in compression is equalto:

Video Solution
Question 67

A concrete beam prestressed with a parabolic tendon is shown in the sketch. The eccentricity of the tendon is measured from the centroid of the cross section. The applied prestressing force at service is 1620 KN. The uniformly distributed load of $$\frac{45KN}{m}$$ includes self weight.

The stress (in $$\frac{N}{mm^{2}}$$) in the bottom fibre at Mid Span is
