Solution:

A RC beam curved in plan is designed for

Bending moment and Shear

Bending moment and torsion

Shear and torsion

Solution:

What shall be the width-to-thickness ratio for a single angle section of Class 1 to prevent local buckling? (Take fy = 250 MPa)

9.4

12.5

6.3

7.8

Solution:

In the case of a laterally unsupported beam, the design bending stress is governed by

Lateral torsional buckling

Shear lag

Yield stress

None of the above

Solution:

As per IS 456:2000 for M20 grade concrete and plain bars in tension the design bond stress = 1.2 MPa. The stress in the HYSD reinforcing steel bars in tension =360 MPa. The required development length, L_d, for HYSD bars in terms of the bar diameter is ______ φ. (where φ is the diameter of the bar.) Answer upto three decimal places.

Solution:

The critical bending compressive stress in the extreme fiber of a structural steel section is 1000 MPa. The yield strength of the steel is 250 MPa, the width of the flange is 250 mm, and the thickness of the flange is 15 mm. According to the provisions of IS: 800-2007, the non-dimensional slenderness ratio of the steel cross-section is:

2.05

0.65

0.50

1.05
