Analysis of Prestressing in Precast Prestressed Concrete Beams
Knowledge of prestressing force’s value is in the case of prestressed concrete structure the most important basis for defining load-carrying capacity and remaining service life. Numbers of prestressed concrete structures are about to reach their limit of

Simulating the behavior of prestressed beams with different degrees of prestressing [PDF]
The paper covers numerical analysis of an experiment with five T-beams that are loaded to failure. The beams are designed to have the same ultimate bearing capacity with different ratios of prestressed to classic reinforcement. A detailed overview of the experiment is shown with exact section dimensions, as well as exact position and ratio of ...

STRENGTHENING BEHAVIOR OF STEEL BEAMS UNDER VARIED ECCENTRICITY LOCATIONS AND JACKING STRESS [PDF]
Thirteen simply supported steel beams were tested to explain the effect of strengthening by external prestressing strands. All of these beams have the same steel section, clear span length and strengthening by two external prestressing strands.

Stage-by-Stage Prestressing Arrangement Design in the Design of Bridges with Hybrid Internal and External Prestressing Tendons [PDF]
In the design scheme of a bridge with external prestressing tendons and hybrid internal and external tendons, the internal tendons can bear the load in cantilever casting construction, the external tendons can bear the superimposed dead load and the ...

COMPARING THE RIGIDITY OF THE PRESTRESSED AND NON-PRESTRESSED FOUNDATION [PDF]
If compared with reinforced concrete, the prestressed concrete is able to resist higher loads before cracks develop. As cracks reduce considerably rigidity of the element, the prestressed element can be regarded as rather rigid. The article compares the rigidity of the prestressed and non-prestressed foundations in two axes.

Multi-Step Prestressing with Hybrid SMA Wires
Prestressing force is induced in reinforced concrete (RC) structures to improve their load-carrying capacity. Generally, the prestressing strand of an RC structure is tensioned using a hydraulic jack, which decreases its workability.

EFFECT OF PRESTRESSING STRANDS ON THE LOAD DEFLECTION BEHAVIOR OF STEEL BEAMS [PDF]
Seven simply supported steel beams were tested to explain the effect of strengthening by external prestressing strands. All of these beams have the same steel section, clear span length and the strengthening samples implemented by two external ...
