Prestressed Concrete Design: Deflections

The concrete beams deflect upwards due to the application or transfer of ______.

The bending moment at every section is the product of the ______ force and eccentricity.

The tendon profile itself will represent the shape of the ______.

At the time of transfer of prestress, the beam ______ up due to the effect of prestressing.

The self-weight of the beam induces ______ deflections.

The cracks of limited width are acceptable under occasional over-loads or even under working loads according to the ______ recommendations.

The load-deflection curve is approximately linear up to the stage of ______ cracking.

Beyond the stage of visible cracking, the deflections increase at a faster rate due to the reduced ______ of the beam.

In the post-cracking stage, the behaviour of the beam is similar to that of ______ concrete members.

A knowledge of the load deformation characteristics of ______ members is essential to comply with the limit state of deflection.
