Reason : A cantilever sheet pile derives its stability from active and
passive earth pressures.
Q.No. 10 : No Change.
Reason : IS:800 – 2007
Clause 8.2.1.5
Q.No. 12 : No Change.
Reason : Vibrating rollers are used for the compaction of coarse grained
soils.

Q.No. 16 : No Change.
Reason : Real and imaginary
Q.No. 20 : No Change.
Reason : The connection for the transfer of small end moments are
called clip moment or light moment connection.

Reason : The effective length of a battened column is increased by 10%
as per IS:800-2007.
Text of page 8
Q.No. 26 : No Change.
Reason : By virtual work principle
external work = Internal work
= MP(Q) + MP (2Q),
Q.No. 27 : No Change.
Reaosn : Beam-columns are the structural members subjected to axial
compression and bending moment.
Q.No. 29 : Deleted
Reason : The question is not complete as the fixity conditions are not
mentioned in the question.
Q.No. 33 : No Change.
Reason : Shear strength is a function of c, Φ and σ or c’, Φ’ and σ’
Q.No. 40 : Deleted
Reason : The force in the redundant member is given by
∑
X=
∑
When the area of redundant member is doubled, then the ∑ will remain
unchanged. Since the forces P is redundant and is equal to zero. But the
term ∑ will decrease. Hence the force X in that member will increase,
but its value will be less than twice.
Q.43 : No Change
Reason :

Q.No. 44 : The Provisional answer is option 'C' But the Correct answer is
Option A.
Reason : Trusses are economical for large spans and heavy gravity
loads.
