The partial factor of safety for resistance governed by ultimate strength is:

1.10

1.5

2.0

1.25

Solution:

If 20 mm rivets are used in lacing bars, then the minimum width of the lacing bar should be:

60 mm

80 mm

100 mm

40 mm

Solution:

What is the partial safety factor for a combination of dead load (DL) and live load (LL) for the limit state of strength?

1.2

1.0

1.5

0.8

Solution:

Which of the following is a disadvantage of steel?

High strength per unit mass

High durability

Reusable

Poor fire and corrosion resistance

Solution:

The maximum permissible deflection for a gantry girder, spanning over 6 m, on which an EOT (electric overhead travelling) crane of capacity 200 kN is operating, is

8 mm

10 mm

12 mm

18 mm

Solution:

The number of independent mechanisms (n) is related to the number of possible plastic hinge locations (h) and the number of degrees of redundancy (r) by the formula:

n = h - r

n = h / r

n = r + h

n = r - h

Solution:

As per the elastic theory of design, the factor of safety is the ratio of

working stress to stress at the limit of proportionality

yield stress to working stress

ultimate stress to working stress

ultimate load to load at yield

Solution:

Which of the following factors is included in the limit state of serviceability?

Fracture due to fatigue

Failure by excessive deformation

Deformation and deflection adversely affecting appearance or effective use of structure

Brittle fracture

Solution:

What is meant by a plastic hinge?

zone of non-yielding due to flexure in a structural member

zone of bending due to flexure in a structural member

zone of yielding due to twisting in a structural member

zone of yielding due to flexure in a structural member

Solution:

What is the Principle of Virtual Work in plastic analysis?

Work done by the external forces equals the work done by the internal forces

Work done by the external forces isn't less than the work done by the internal forces

Work done by the external forces is more than the work done by the internal forces

Work done by the external forces is not equal to the work done by the internal forces
