prestressed

The studies related to the prestressed NSMR focused mainly and experimentally on the prestressing force due to the absence of appropriate prestressing system for NSMR.

Although the use of unbonded tendons as the major prestressing technique in design and rehabilitation has been favored for reasons of ease of construction, cost-effectiveness, and maintenance, the overall structural behavior of prestressed with externally unbonded tendon under flexural loading is yet to be well understood, as little work has been done in this field [1].

Application of prestressed steel stayed columns provides substantial increase of these values at the cost of rather higher expenses for fabrication and assembly, and may also affect aesthetics of the structure (Fig.

One method indirectly prestressed FRP sheets by cambering the flexural member [2].

Segmentally erected prestressed bridges are becoming very popular for moderate spans all over the world (Ketchum, 1986).

In the structure of prestressed anchor frame beam, the reinforcement mechanism of the combination of anchor and frame beam is through the powerful prestress to strengthen prereinforcement slope.

Prestressed concrete transmission pole structures; recommended practice for design and installation.

Usage of prestressed cable truss is another method of fixing the problem of increased kinematic displacements under the action of unsymmetrical load (Fig.

"QDC continues to experience strong and robust demand for its precast and prestressed concrete products for both commercial and residential construction projects throughout Saudi Arabia and Qatar," says John Dobbs, who was appointed as CEO and general manager of QDC in June.
