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 ...

Shear resistance of prestressed concrete beams with the constant and variable height [PDF]
MATEC Web of Conferences, 2021 One of the methods of increasing the efficiency of using prestressed reinforcement involves transferring a certain amount of longitudinal tensioned reinforcement from the tensile zone in the span to the upper compressed zone on the support, where it is ...

Numerical shear of post-tensioned beams with inverted-U shaped reinforcements
Magazine of Civil Engineering, 2022 Previous works verified that, compared to conventional stirrups reinforcements (or closed stirrups reinforcements), the inverted-U shaped reinforcements improve the performance of the flat slabs in terms of failure mode and load capacity.
