Civil Engineering :: Design of Steel Structures
- The portal bracing in a truss bridge is used to
- The ratio of plastic section modulus to elastic section modulus
- The web crippling due to excessive bearing stress can be avoided by
-
Battening is preferable when the
i) column carries axial load only
ii) space between the two main components is not very large
iii) column is eccentrically loaded
The correct answer is -
Bearing stiffeners are provided at
i) the supports
ii) the mid span
iii) the point of application of concentrated loads
The correct answer is -
The effect of racking forces is considered in the design of
i) lateral braces
ii) chord members
The correct answer is -
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 - Select the correct statement
- In case of timber structures, the form factor for solid circular cross-section is taken as
- The effective length of a battened strut effectively held in position at both ends but not restrained in direction is taken as
