Operation of pre-stressed span beams of bridge cranes taking into account load combinations
Trudy Odesskogo Politehničeskogo Universiteta, 2022 The paper considers issues related to increasing the bearing capacity of span beams of bridge cranes by means of pre-stressing. It is known that the work of the span structure of the crane with pre-stressed beams takes place under the same conditions ...

Influence of changes in the prestress force on dynamic specifications of the prestressed concrete beam [PDF]
Numerical Methods in Civil Engineering, 2020 Pre-stress techniques tend to increase cross-sectional capacity and optimize design. Such features have made these techniques rather popular. Over time, these structures tend to fail, and the reduction of pre-stress force over the lifetime of the ...

Behavior of Pre-stressed Concrete Deep Beams
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Six simply supported deep beams were tested to show the influence of prestressing strand on the behavior of reinforced concrete deep beams. All tested beams have same gross sectional area (42000) mm2, compressive strength (30) MPa, clear span length (1000) mm, longitudinal and vertical reinforcement and the strengthened beams ...
