For a steel grillage footing to support two unequal column loads

Civil Engineering : Steel Structure Design - Quiz(MCQ)

trapezoidal shape is used for the base footing

projections of beams on either side in lower tier are such that bending moments under columns are equal

bending moment under the columns are kept equal to the bending moment between to two columns

All of the above

Correct Answer : All of the above

Explanation : * trapezoidal shape is used for the base footing
* projections of beams on either side in lower tier are such that bending moments under columns are equal
* bending moment under the columns are kept equal to the bending moment between to two columns
* line of action of the resultant of two column loads, is made to coincide with the centre of gravity of the base of the footing

Which of the following is not a parameter for decrease in strength of slender member?

residual stress

seismic load

initial lack of straightness

variation of material properties

Correct Answer : Option (B) : seismic load

Explanation : The decrease in strength of slender member is due to following parameter : imperfections- initial lack of straightness, accidental eccentricities of loading, residual stress, and variation of material properties over the cross section.
