## 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

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

## Design of Steel Structure The best arrangement to provide unified behaviour in built up steel columns is by

tie plates
perforated cover plates
battening
lacing

## Design of Steel Structure The mechanism method and the statical method give

lower and upper bounds respectively on the strength of structure
upper and lower bounds respectively on the strength of structure
upper bound on the strength of structure
lower bound on the strength of structure

## Design of Steel Structure Other conditions being same, the load factor in indeterminate structures is

Unpredictable
More than the load factor in determinate structures
Equal to load factor in determinate structures
Less than the load factor in determinate structures

## Design of Steel Structure Hudson’s formula gives the dead weight of a truss bridge as a function of

top chord area
effective span of bridge
bottom chord area
