Secondary transfer length and residual prestress of fractured strand in post-tensioned concrete beams

Frontiers of Structural and Civil Engineering   Pages 388-400 doi: 10.1007/s11709-022-0809-1

Abstract: An experimental study is performed on five post-tensioned concrete beams to explore the effects of differentdeveloped and used to predict the secondary transfer length and residual prestress of fractured strand in post-tensionedconcrete beams.Results shows that the fractured strand can be re-anchored in concrete through the secondary anchorageWhen the fractured strand is fully anchored in concrete, a minor prestress loss will appear, and the

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 5,   Pages 1020-1035 doi: 10.1007/s11709-019-0534-6

Abstract: The effects of important parameters (beam reinforcing plates, initial post-tensioning, and material propertiesof steel angles) on the behavior of hexagonal castellated beams in post-tensioned self-centering (PTSCThe web-post buckling in hexagonal castellated beams has been identified as the dominant failure modewhen excessive initial post-tensioning force is applied to reach greater bending moment resistance,so it is required to limit the highest initial post-tensioning force to prevent this failure.
