Question 1
If a beam is likely to fail due to high bonding stresses, then its bond strength can be increased most economically by
Question 2
A singly reinforced rectangular concrete beam has a width of 150 mm and effective depth of 330 mm. The characteristic compressive strength of concrete is 20 MPa and the tensile strength of steel is 415 MPa. Adopt the stress block for concrete as per IS 456-2000 and take the limiting value of depth of neutral axis as 0.48 times the effective depth of the beam for considering as a balanced section. What is the likely approximation for the limiting value of the moment of resistance of the beam?
Question 3
Find the effective width of flange for an isolated T-beam having l0 = 3.5 m, depth of flange = 200 mm, width of rib = 450 mm and actual flange width = 1.6 m
Question 4
Consider the following cases in the design of reinforced concrete members in flexure:
1) Over-reinforced section
2) Tension failure
3) Compression failure
4) Under-reinforced section
Which of the above cases are considered for the safe design of R.C members in flexure?
1) Over-reinforced section
2) Tension failure
3) Compression failure
4) Under-reinforced section
Which of the above cases are considered for the safe design of R.C members in flexure?
Question 5
Consider the following statements:
The modification factor for limiting span to depth ratio
(i) Increases with increase in span (Span > 10m)
(ii) Increases with increase in compression reinforcement
(iii) More for flanged width as compared to rectangular width
(iv) Does not depend on span (Span < 15 m)
Which of the above statements are incorrect?
