Assessment of Mechanical Properties of Corroded Prestressing Strands [PDF]
Applied Sciences, 2020 The corrosion of prestressing steel in prestressed concrete bridges is a critical issue for bridge maintenance. To assess structures with corroded strands, it is necessary to define the mechanical properties of the strands and their influence on the structural behavior.

STRENGTHENING BEHAVIOR OF STEEL BEAMS UNDER VARIED ECCENTRICITY LOCATIONS AND JACKING STRESS [PDF]
Journal of Engineering and Sustainable Development, 2020 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.

Modeling of bond stress-slip relationships of mono-prestressing strands with H-anchorage dead end
Ain Shams Engineering Journal, 2023 One of the innovative structural techniques is post-tensioning members with H-anchorage dead end (onion dead end). The H-anchorage dead end is an economic anchorage technique as it enables the use of one anchor device at the live end only where the ...
