Sketch the loop reinforcement, hair-pin
bars in end blocks.
Sketch the correct arrangement of sheet
cage in anchorage zone.
3. Define two stage constructions.
· One-stage construction:
Construct and initialize the object in one stage, all with the
construction: Construct and initialize
the object in two separate stages.
constructor creates the object and an initialization function initializes it.
4. Write any two general failures of prestressed
deformation of the pre-cast concrete
units during construction
Manufacturing inaccuracies led to out of
tolerance units being delivered to the site under investigation and may have
affected the ability to achieve a good seal.
the importance of shrinkage in composite construction?
The time dependent behavior of
composite prestressed concrete beams depends upon the presence of differential
shrinkage and creep of the concretes of web and deck, in addition to other
parameters, such as relaxation of steel, presence
untensioned steel, and compression steel etc.
