## Design of Steel Structure In a gusseted base, when the end of the column is machined for complete bearing on the base plate, then the axial load is assumed to be transferred to base plate

Fully through fastenings
50% by direct bearing and 50% through fastenings
Fully by direct bearing
75% by direct bearing and 25% through fastenings

## Design of Steel Structure If the loaded length of span in meters of a railway steel bridge carrying a single track is 6 m, then impact factor is taken as

0
0.5
1.0
between 0.5 and 1.0

## Design of Steel Structure The moment-curvature relation at a plastic hinge is

linear
constant curvature for all moments
parabolic
constant moment for all curvatures

## Design of Steel Structure Lacing bars in a steel column should be designed to resist

Shear force due to 2.5% of the column load
Bending moment due to 2.5% of the column load
Both (A) and (B)
2.5% of the column load

## Design of Steel Structure Study the following statements.i) Top lateral bracing prevents the sidesway buckling of the chord.ii) Sway bracing keeps the rectangular shape of the bridge cross-section.iii) Sway bracing transfers the load from top of end posts to bearings.The correct answer is

all (i), (ii) and (iii)
both (i) and (ii)
only (i)
both (i) and (iii)
