Advantages of
using post-tensioning
for your next Repair, Rehabilitation and Strengthening project:
Structural
Integrity: The
strength and serviceability of a structure that has experienced
deterioration can be evaluated and restored to its original or greater
strength and serviceability.
Versatility:
External
post-tensioning can be used to increase
and/or restore, the capacity of most any structural element
(beams and girders, one-way slabs, two-way
slabs) made of any material (prestressed concrete, nonprestressed
concrete, structural steel, wood).
Minimal
Disruption: Ability to
strengthen an
existing member with minimal headroom requirements and no significant
added weight. Strengthening can be
done with little or no disruption of existing
utilities. Retrofits
can
typically be
executed concurrently with normal building operations without any large
shutdowns or closures.
Active
Loading: External
post-tensioning applies active loads directly
to the strengthened member so it can supplement existing capacity to
any
desired degree. Other strengthening
systems, such as added steel, concrete beams, or FRP wrapping are
passive;
in the absence of jacking, the strengthened member fails to mobilize
the
strengthening system.
