The deformation of concrete, the relaxation of the prestressed steel strand, the corrosion of the steel strand, and the creep of concrete will cause the loss of prestress.
They also do not fully account for the effects and losses of the prestress. Moreover, even through these complex methods, there is no guarantee of highly accurate predictions.
In order to decrease initial deflection prestress load of CFRP should be transferred in to the strengthened beam.
The authors reported that the introduction of prestress could delay the bond failure since the prestressed NSMR specimens failed through the rupture of the FRP reinforcement [9].
At first, we set an initial temperature value and a temperature drop value for reinforced unit to make reinforced unit generate contraction deformation; this initial strain will let the reinforced steel pretensioned as prestress in the finite element model.
Where, f'ci is the compressive strength of concrete at the time of initial prestress. Stresses at top fiber (s1) and bottom fiber (s2) of box girder section due to construction stage loads could be calculated as follows (Eqs.
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.
Spokane, WA, August 17, 2012 --(PR.com)-- Oldcastle Precast - Central Pre-Mix Prestress located in Spokane, WA was contracted to manufacture and deliver the prestressed concrete WF 83 Super Girders used to construct the new Appleway Bridge over the Spokane River just west of the Washington-Idaho border.
The experimental program was developed with two main objectives: to study the evolution of the prestress value applied to the structure and to observe the bridge structural behavior under the effect of loads simulating the action of a standard vehicle.
Many techniques of ultrasonic nondestructive characterization of the material and the prestress in the material are based on the results of the analysis of the nonlinear effects that occur in wave interaction processes.
